K, here goes. I changed the throttle body assembly today...no easy task but here's what happened.
It idled at 1100 on start then within 2 to 3 minutes, kicked down to 800. Every thing seemed fine, didn't hear no skippity-do-dah and almost got my hopes up.
Then for shits-n-giggles, I wanted to see what would happen if I tapped the gas pedal. When I did, the RPM's went up to 1500 and stayed there. I tried to kick it down and it went up to 2000 and stayed. Tried a little tap on the pedal and it jumped to 2300 and stayed. Shut her down and restarted and she was at 1500.
Prior to this job the idle screw on the old assembly was out nearly all the way. Whereas with the new one, it is in nearly all the way. This assembly comes from the well reknowned Jerry Lemond and he told me the settings were either right where they need to be or pretty darn close. I have much faith in Jerry and I believe my old one was way off.
One thing worth noting is that when I took the old assembly off, I had to take the bracket off that attaches to the bottom of the throttle assembly and holds a throttle cable that goes vertically down towards the bottom of the intake. Not the front one that rests on the air breather and goes into the passenger/driver compartment. The vertical cable is attached to this bracket by two nuts...one underneath and one on top. While removing it I had to completely remove the upper nut but didn't think I bothered the lower one so I figured I'd be all set. What is this cable and could it be causing my current idle situation
Or, is this just a typical idle adjust problem. I had the battery disconnected while working on it and thought that the ECM would readjust the settings based on the new assembly but should I go and do the idle adjust properly or is this a bigger problem
I'm on my way back out there to check and make sure the cable/s are not sticking while accelerating but beyond that, I don't know for sure what to do next and I don't want to screw anything up that isn't already messed up.
I'm so close I can taste it. Besides the idle jumping while depressing the pedal, it ran smooth and maintained at whichever RPM it reached.
HELP...I'll be back to check in.
dawn...
