TPS Sensor?

[JimCRX]

This problem has gotten worse now. I just had my valves adjusted because they were tapping bad. I took off my IAVC cleaned it and all and I still have the idle problem. I even put a resistor on the IAVC so the idle would go by the screw only and still nothin. Whenever I come to a stop it will constating rise and fall, rise and fall etc...Now like say I shift at 3,500rpms it'll hang and idle at like 3,000 for a minute then drop and etc. I was told that this probably is a bad TPS Sensor. What exactly does it control? I know it's on the throttle body and it's mounted in it pretty good so I would probably have to get a whole TB?

TPS controls most anything that has to do with electrics and intake... does it bog or run poorly when you're at WOT? or does it seem to do funny stuff through out the time you push the throttle? it sounds like a bad IAVC it's annoying but it doesn't mess anything up. mine does it and i'm still pulling some good times.

possibly a intake manifold leak, throttle body or a vaccum leak of some sort. make sure every thing is torqued to oem spec and vaccum lines are routed correctly.

Yeah, it runs poorly, but doesn't bog. I doubt it's the IAVC. I disconnected the IAVC and hook a resistor up to the plug so it wont go by the IAVC, only the screw and that didnt make a difference. It seems to be hanging around 2-3,000rpms. Like if shift at 3,200rpms, it will sit and idle around 3k rpms for like a minute then drop and rise hang a little bit, drop and rise etc...Vaccum lines are fine and the bolts are fine.

i have the same problem on my b16 crx. my idle was rising and falling the same as yours. i unplugged the sensor on the iavc for now and it fixed the problem. i tried to clean the iavc and it didn't do anything so i am going to the yard and pulling off another one.
