I got really tired of my idle surging so I bought everything i could think of to fix it. I replaced the TB seals, put in a fiav block off plate (kept the IAC-they make a special plate for it), new biss screw, o-ring, and rubber cap, TB gaskets, aeromotive AFPR and adjusted the TPS. Now it idles perfectly at 800rpm. Just thought I would share for anyone that was having the same problems. If anyone needs any help or suggestions let me know. Have a good one guys.

 

So much for daignosing your problem lol, well at least your fixed it.

 

how long did all that take you?

 

Congrats : )

 

what was your idle doing b4 all this work cause i have a problem with mine right now. i start it up and it will die if i dont rev it once, but after that one rev its all good . you got any ideas. i was thinking of changing my tps and my ics? not sure what the problem is though.

 

haha that's sweet man, congrats

 

It only took me about an hour once all the parts arrived. 98gstspy, my idle was really high when i first started my vehicle. I could screw the biss screw all the way in and it still wouldn't drop down. Every so often it would also surge from 1500-3000rpms. Then after it was warm it would idle really low and sometimes die like yours. I would say make sure the tps is set correctly, or if it is old, replace it. Its easier to adjust if you have a data logger or if you watch the voltage on the safc. I hope that helps brother. Thanks guys

 

well i know that my tps is old so you think i should replace it then. i was also looking into the ics you think that could b it to?

 

I would definately replace the tps, but as far as The IAC i would wait and make sure there are no leaks first. If you have leaks in the throttle body the IAC won't be able to compensate for them after a certain point. If fixing the leaks and the tps doesn't fix the problem, then start testing the IAC.

 

ok well i gotz to wait until i get paid b4 i can get a new tps. ill keep you up dated. but you say you think its the prob. so i will trust you.
