SO it a 95 GSR with a JRSC on it. All the tunning first off was unchanged. About two months ago the car started to idle at 3000 rpms. It will stay there until warn. Afterwards it will bounce from 2,500 to 3,000 rpms?? I am lost on this one trying to see if anybody knows a cure. I was thinking the TPS sensor. I think i might chnage it out for shits and giggles.
Thanks

iac?any codes?

 

Dude this is retarded of me but, i forgot where the two wires connector is to jump it with my fabed cable. On my old teg i had pulled it down from somewhere i don't remember ?? I thought it was like green. Its been a while since i owned a OBD1 car.

That was the first thing that came to mind was the IACV, or TPS. He (the owner) says the IAC is new ?

I'll pull the codes later as soon as i figure out where it is !!

 

the code extraction port is under the glovebox it should be a little grey plug i beleive an you just put a jumper in there and count the blinks honda-tech .com has an excellent write up on how to pull the codes from an obd1 car.....

 

Oh yea i was thinkin it was by the ECU.
Thanks dude i'll check back when i get the code.

its letting you know a supercharger shouldnt be on a 4 cylinder.

 

6 coolant temp sensor
7 throttle angle ? thats all i found on it so far
14 Electronic air control (i'm guessing the MAF)
22 VTEC oil pressure switch

Well thats what he has. I'm doing searches to find more info. any help is appreciated. This is the first JRSC i meesed with so anything to look out for let me know.

 

there's 2 connectors that i've mixed up before, and it cause the car to run crappy and give CEL's. i believe it was tps and map, can't remember for sure, but check to make sure all sensors were hooked up properly. a lot of them have similar connectors and can be accidentally mixed up. hope this helps.

 

Yea but would it raise the idle to 2-3k? But, i read that somewhere else. I'll check it out.
