ok....3 seperate problems, two possibly interlocking.

background:
'85 4runner, 22re, auto. rebuild not more than 500 miles ago, complete, bored over .030, crank ground .010, cam almost identical to engnbldr-rv2 cam from them, hedman headers, flowmaster 50 series, and i was stupid enough to mess with the AFM (its almost positively at the original location, but i never resiliconed the lid so there is a chance of water damage..) new injectors, new injector side wiring harness, new fuel filter, new plugs, cap, rotor and wires. can't think of anything else, just ask and i'll tell.

problem 1: rear window doesn't go down. tried to open up the console switch, but the spring went to god knows where. So i scavenged a 2nd gen switch and its a plug-in affair. could wiring in the switches be different? I got a new-to-me circuit board (the driver side, beside seat belt retractor one), and wiper switch is NOT on, and wire IS plugged in on canopy, and the canopy bolt is contacting the sensor correctly. The key switch for the window doesn't work, as well. any ideas? oh yeah--the fuse isn't blown <img src="/forums/images/graemlins/smile.gif" alt="" />

problem 2: engine sounds fast, but is unbelievably not. i mean unbelievably, unremarkably not. i loose speed uphill, at the slightest inclination, with accelerator maxed out. I burn through incredible rates of fuel--about half a tank in about 60-70 miles. changed plugs once due to fouling out (autolites), and am about to r&r new ones (NGK) but dont feel like having those fouled as well. Am about to change fuel filter as well, just to double-eliminate a problem. and like i said, spankin new injectors, and cleaned out the TB, for s#!ts and giggles. help me diagnois, please!!

problem 3: possibly contributing to losing speed uphill and gas consumption, my auto tranny will not downshift unless a complete, or damn near complete stop is accomplished. never used to have this problem. still feels strong, kicks like a truck when i shift gears, but thats the only way i dont end up doing 30/40 going uphill on I-5, is by manually shifting. this is NOT a good idea on a rig that is 30k shy of 300k, on for as much as i know an OE tranny. Keep in my this rig is rolling on 31's, but i can never recall it being this much of a turtle before the rebuild. it was slow, but this is like golf cart slow <img src="/forums/images/graemlins/smile.gif" alt="" />.


hhellllp mmmeee! anybody willing to make the trip to Olympia, iv'e got an OK set of tools in an 11drawer rollaway, and ill supply the beer and good times, and reimburse for the gas to come on over. oh yeah, and ive got a couch for ya if it gets alittle lengtturns into an all nighter. thanks for the help in advance, guys!!

Rear window troubleshooting tips.

The engine and tranny problems may be related, engine temperature related, its running cold and the ECU is richening up the mixture and the A/T ECU is restricting the shifting to warm up the engine as well. Maybe bad thermostat or one of the engine temp senders is bad, giving false temp readings to the various ECUs. And last but not least, it may be the infamous throttle position sensor. Check eveything out before throwing lots of parts at it.

Don't forget to check the tranny kickdown cable adjustment... Very important for proper shifts/downshifts.

Crap, forgot you moved back into the area! <img src="/forums/images/graemlins/ignore.gif" alt="" /> I mean, good to hear that it is at least running! lol Sounds like theres a couple of things not jivving with the EFI system. Crappy gas mileage, no power...have you extracted the codes to see if anything is being stored? A bad O2 sensor can cause the fuel problems as well as what Roger mentioned. And I would check his suggestions first. Then move onto some of the electrical. I still have a spare AFM and a few things left over since finishing up my 87' 4Runner justincase and all that.

even though most problems arent dont forget the simple stuff like the tranny fluid

That last sentence is by far the best advice anyone could give.

Once comment, though Roger. Since his tranny isn't down shifting, I'd doubt it's temperature related. Usually the tranny doesn't upshift if the engine is too cold - in an attempt to warm the engine up faster with higher revs.

Did you put a new O2 sensor in when you built the engine? IF so, is it an aftermarket? I've found that many aftermarket sensors are not "long" enough to get into the exhaust streem in a header. The factory Toyota O2 sensor was over 1/2" longer than the aftermarket one I ran for a while - I had a similar mileage problem as you.

Did you have the head shaved or the block decked? If so, your cam timing may be off - this too will affect power and mileage.

Lastly, I'd throw a borrowed non-molested AFM at it for a couple of days and see if that makes a difference.

This my friends is what happens when you modify an engine with a computer in it... It no likee zee chenges <img src="/forums/images/graemlins/evil.gif" alt="" /> I am french, why do you think I talk with this ourraageous accente!

Sorry about that... I know its not a check I like to do on a 500 mile engine, but check out that compression and see if everything seated properly. About the cam... There aren't any "identical" cams. I've talked with EB on that one. Most are... well... I'll let him expain that one to you.... <img src="/forums/images/graemlins/shocked.gif" alt="" />

I've also heard aboot a problem with cams/header combos.. Mostly the EFI/EBcam/LCEheader... but I guess it could be a problem with that combo too... He's supposed to be testing a modded stick that makes up for the problem. Something about the O2 and the AFM getting confused... I'm a carb guy so bear with me! heh

Hopefully she broke in correctly.. If I'm not mistaken with a auto tranny it shifts with load on the tranny.. If your engine isn't loadin it up, it doesn't shift... Eh, I've got a manual tranny to boot!

You *should* be running 15's in the quarter mile with that setup, well at least with how much money got thrown at it!

Let us know what you find. Run a comp test if the electrical comes out fine. When I first started reading, sounded like ultra low compression to me...

Ok....like i said, ask and i tell <img src="/forums/images/graemlins/smile.gif" alt="" />

Roger:
Ive read and re-read your window site....1) i cant seem to determine where to put power on the window regulator itself to test the unit as a whole and 2) everything i tried from there, didn't help. Replaced thermostat twice, and one of the temp switches below it, the one with the yellow male end. And for the TPS, iv'e tried adjusting it several times, but dont really understand your site, so i did it to the best of my ability..it appears to be in correct position.

DRTDVL:

ill look into that...good thinkin.

Darin:

Hey buddy! yup been back for a little bit...at least its running <img src="/forums/images/graemlins/smile.gif" alt="" /> brand new O2, from Bosch, had OE toyo in there, no difference before and after. Checked for codes even though no MIL was illuminated, and kept getting my TPS code. wrote it off to retarded comp, because no matter what i did, code stayed. We should talk about that AFM soon...


Rockota:

I did have both head and block deck cleaned up for the rebuild, but nothing worth mentioning. I didn't even need a thicker than OE head gasket, so im pretty sure it wont make much of a difference.

Arbitrary Notion:

Compression was just recently checked, all sitting at 180. i dun a good job ill try and find the stats for that cam, but its nearly identical to that of EB...one thing was off, Darin (esquire) and I have been trying to hunt bugs out of this since about January, and we have touched on the cam many a times.


i love this truck, but im about to beat it like a red-headed step child.

oh and about engine temp, its fine. as a matter of fact its alittle better than fine. when it rains here, those droplets evap damn near immediately after hood contact. no other car ive ever driven has done that *so* quickly. I cant even wash the damn thing in 60 degree overcast weather after driving it for 10, 15ish minutes without the water/soap baking on the hood so, i just dont wash. hehehe dirt is more becoming, anyway.

The rear window relay module basically puts 12V across the rear window motor, if one side gets 12V and the other side ground, motor turns one way, swap the power and ground leads and it turn the other way, so you would apply power directly to the motor to bypass all the interlocks. Best to follow the troubleshooting steps as outlined on my page, they are roughly in the order of easy to hard to test things and also check the oh-so-common problems of the missing shell interlock bolt and the rear window wiper that is not fully retracted. Those two problems cause probably 95% of all rear window problems.

What temp. and brand t-stat are you using? I find only the real Toyota brand t-stats work reliably over the long run.

What is causing you difficulties on adjusting the TPS? Maybe I can clarify the directions, and have you checked out the really simple step-by-step hints Frankenyota added:

Step by step times for adjusting the idle setting

Basically you want to test the unit to see if the overall readings are within spec., that is do you get a resistance that is proportional to throttle position? You do this with an ohm meter and just check the resistance readings between terminals as noted.

If all the basic readings are OK, then you need to adjust the IDLE sensing part so make the TPS detect a closed throttle. You do this by loosening the TPS itself and rotating it on the throttle body until it reads the correct IDLE setting on the meter.

<img src="/forums/images/graemlins/confused.gif" alt="" />Just curious,does the 85'22re have that "POS" auxillary air valve on it.If so,make sure that thing isn't hung open when the motor is warm!The best move for anybody is to switch to the newer style TB and intake plenum.That swap alone has solved so many problems on my 87'. <img src="/forums/images/graemlins/cheers.gif" alt="" />Hope you find the problem soon!
