Rep Power: 269 Bored Throttle body
I just got my bored throttly body and i installed. The idle is good until i press the gas then it flucuates just like it had when i had an air leak. I checked all the vaccuum and i don't think i have an air leak. What can i do to fix this? It goes from like 1250-1500 it sounds like **** and its embarassing other than that it works great

Rep Power: 787 The main problem I had was severe bogging when pressing the gas from a stop. But I think it might be because I put on a tb from manual instead of auto. I had your problem too, its solved by resetting the ecu and doing the idle learn. Its a must if you swap the tb. But I don't think a bored tb is that good for na. turbo is a different story...
to do the idle learn, warm up the car to temp by driving. Turn off, remove FI ECU fuse from box by battery. Put back. Start car, let idle 10 mins without pressing gas and without using accessories. After 10 mins, turn car off and then back on. Go drive it around at various speeds. It may take a few days to relearn the closed loop fuel maps. But the idle should be fine right after you do it.

Rep Power: 787 manual or auto? there is a difference. if you use maxbore.com, he actually replaces the tps rivets with screws so you CAN take it off.

Rep Power: 269 It started again even after that i tried doing the idle learn procedure reving it to 3000 until the fans come on then letting go it still didn't work. I tried adjusting the idle and thats when i figured out that at 1800 and above the car idles good it won't go up and down so what should i do? It sucks have the idle that high but thats the only place it won't do that

Rep Power: 428 is your check engine light on at all? Either try like gearbox said and reset the ECU and do the idle relearn again, or phycially check the IAC and the TPS voltage. Or try putting on a different TB and see if the problem goes away.

Rep Power: 787 first answer these questions: did maxbore.com do it? are you using the correct model (ie manual trans tb for manual car)? is the throttle cable overtight (it needs .5inches of play when you push down on the cable before it moves the lever)?

Rep Power: 350 that iac crap is a real bitch - mine needs to be cleaned all the time for some reason in order for the car to idle properly. good job on figuring it out.
