Idle problem in my B20/vtec???

[CRVTEC EG]

I have a GSR head on a CRV block......When i start the car, the revs jump up to 3k then they start bouncing from 1k to 2k rpms, it doesn't go away after the car warms up. I'm leaning towards a bad TPS sensor but i wanted to see what you guys thought........thanks a lot

check the pcv, iab, or iacv, or it could be the tps just check there voltage and also there vacum to make sure its working properly.

my swap did that too(h22).. i messed with the tps and idle screw
dont know which made the diff.. i think tps

isnt the fix to measure ohm or somthing?

YA THATS WHAT I MEANT TO SAY JUST CHECK THERE OHMS AND ALSO THE VACUM OF THEM.

sounds like an idle air control valve or a vacum leak to me. i would look at those 2 first.

Thanks for the fast replys, i'm gonna go check the iac right now

vacuum leak.

OK, got it guys, there was a loud squeling noise coming from the intake so i took it off and i covered the holes in the throttle body with my fingers and it idled like normal.....so i took the iac apart and the white plastic part inside that screws in, was lose and it fell out, i tightened it and put it back togehter now it idles the best it ever has.

Thanks for all the help
