that helped me some but what else could cause it so i can narrow it down but the carb sounds like my problem what would cause it to run rich

Rich...

Bad 02 sensor
Bad ECT sensor
Bad Bowl vent valve
Bad feedback solenoid valve
Crack in the exhaust manifold
leaky exhaust manifold gasket
General carb fubar
leaking or disconnected vacuum lines

list goes on and on!


You just have to start the elimination process...Just speak up if you have no idea what your doing. I didn't have a clue in 2000 when I bought mine. If you have the factory manual you can pretty much follow the directions to check the sensors. <img src="/forums/images/graemlins/cheers.gif" alt="" />

i think it is my dist. because i can unplug the new vacum advance and it dont change the way it runs and i can move the advance back and fourth a couple of times and it will run fine for a little while any one have any sugestions.or has any body had this problem
thanks donald

I used to work for a machine shop and we had a distributor machine. We would setup street motors, without vacuum advance and set total mechanical advance to fall somewhere in the 30-36 degree BTDC range (24-30 degrees in the distributor with a base timing of anywhere from 6-12 deg. BTDC). By changing advance weights and spring pressures you can set the RPM that the advance starts and the RPM where it's all in. Vacuum advance is only for emissions while cruising (and it does help fuel economy as well). At wide open throttle there is no vacuum being pulled on the vac advance anyway so you really don't need it for power. I don't know what the stock dist. has for total mechanical advance or at what RPM it comes in at, but since the base is 7 deg BTDC, as long as you set it there you should be OK. Unless the mechanical advance is where the problem is.

i got a dist ordered we think that is the problem because we can mess with the advance and it clears up

it probally is catching some were and when we mess with it it frees it up its eating alot of fuel

The factory service manual is available as a free download if you click on this link: The aforementioned Service manual

I put the Chapter 14 "Fuel System" section of the factory service book on my website. Just save the PDF to your desktop and open it when it's done downloading. It's a free download from my site, but be forewarned: it will take you a little while. Very, very informative for anyone with the 32-35DIDEF carb.
