When my FC is cold, the idle will bounce from 1300 RPM to 1500 RPM, but will hold at 1100 RPM when warm. I tried adjusting the stinking idle mix screw when she was cold, and it would stop bouncing, but when she warmed up, it would only idle at 200 - 500 RPM! I thought that I had fixed my idle problems, but I guess not. If it is the damn TPS again, can someone give me GOOD pictures of the process?!?!!?? Most of em i've seen SUCK!

 

Sounds like the thermal wax pellet. Do a search on that, or wait for someone else to explain, because I'm not real sure about it, but my car has the same problem.

 

Really.. Thanks!

 

the 1300-1500 idle while cold is normal. just wait till if fully warms up before you start to adjust the ilde screw on the BAC to get a 750 idle. if you can get it down to 500 it's not the thermo wax. otherwise you would never get it down.

ps can anyone see my sig?? my dam webhost company has been down for like 2 days now $#%#@

 

But if I adjust it down, it won't idle for S*%T! I am lucky for a decent 500 RPm, but it usually a car shuddering 200!

 

are you adjusting the ilde speed control on the BAC or the mixture screw on the shock tower?

 

I did not think there was a screw on the BAC, and what is the shock tower? I am adjusting the screw on top of my throttle body, as I have a 1991 N/A. Explain, and btw, Scott, you are now my hero!

 

opps, I'm pretty sure the 89-91 don't have the shock tower one. ignor that.

 

Cool, so I just adjust the idle mix a little when she is already warm? I have only done it cold! I will try it tomorrow evening, and let ya know how it worked!!


Rico05 is now Scott 89t2's biggest fan!!!

 

Hailers and Mykl are ok too, I guess...
