I am have been having a problem with my car and think I might of finally found the problem. For the past month or so my car is idleing very rough radical idle up and down in 500 rpm. Only at idle. At first we thought it was a vacuum leak well we tested it and no leak anywhere. I since took the IACV off cleaned it replaced the ring gasket, took off the FITV tighten it cleaned it and put it back on. I then tried to fix it with the idle adjustment and reset with no luck. Then today think I found the problem. I am throwing no codes for this problem. I took the TPS or TAS throttle position sensor connector off and it stopped. It threw a CEL for it. I drove it around and it seems like its running great. Never was able to hear the groul of the h22 from 1-3k rpm sounds great. So maybe I am thinking the TPS sensor is bad? what do you guys think? My main question is on the TPS and TAS my old 1.5L hf crx engine has one and it looks to be the same except it is ribited in and mine is screwed it on the h22. So I am guessing if i take the ribits out of the 1.5L hf one and put it on the h22 it should work? My guess is that this part is the same for a few honda/acura applications? TIA-John

 

you can use the tps from your old motor but the lil rivots on it are gonna need to be broken so you can get the tps dialed in accurately.

 

what chassis did the engine harness come out of? what chassis is your crx?

dx, si, hf?

the two outer tps wires are backwards on a DX engine harness..

Just so you know you can just take A cut-off wheel and cut A slot in the rivet's, for a flat head screw driver and they screw right out.
