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
