low idle

[JDMjunkie]

well i fixed the exhaust on my car, and now i have another problem. as you know my car has an H22. i start the car and it runs fine, but when i come back 5 minutes later its idle is really low and it wants to die. i checked the cap,rotor, firing order, plug gap, everything. anyone have any ideas??

Whats the idle speed at...You can adjust with the screw on the tb. My h22A sits at 750-800 RPM normally

well the car isnt mine yet, im helping the guy fix it before he sells it to me, im not sure what the idle speed is at but im going to be working on it on tuesday so ill try that out, is there anyway you could post me a pic of the screw on the throttle body please? thanks alot

questions for ya?

1)- when you say it starts and runs fine...meaning it runs fine cold, then acts up when engine is at operating temp?

2)- whens its sputtering are you getting a cel?

im thinkng you iac/ eacv valve isnt adjusting to load properly. the idle screw isnt fixing the problem, but temp solution. other than that maybe just a disconnected wire or loose wire, or bad oxygen sensor.

other possibilities- alot of tps sensors get messed up in shipping or swaps, ects.

Well here is a pic if your wanting to adjust the idle. I believe you turn it clockwise to turn the idle down and counter-clockwise to turn it up. This is a pic off my F22 but there all located in the same spot on like every motor.

Thanks for posting the pic of the screw, the engine starts up fine, then it starts to act up a few minutes later. there arent any CELs, im not sure what could be wrong.. , also could you tell me where the iac/ eacv valves are?? sorry for the noob questions but this is my first time working on a honda

[JDMjunkie]

The car is throwing a CEL. im not sure what it is yet. when i start the car the idle jumps up and down, and the fuel pressure is bouncing up and down. eventually the car stalls. when i drive it and let off the gas the car stalls. can anyone tell me how to check the CEL code and how to read it?? anyone have any ideas?? thanks alot

well it turns out my O2 sensor was unplugged and that took care of the CEL. also i have a bad fuel line and its building up a lot of pressure, so i think thats why the car is dying, because its getting too much gas. also do i have to reset the ECU because i plugged in the O2 sensor?? thanks

I would reset it anyways if your doing anything that adjusts or changes the parameters that the engine runs itself by. Doing so allows the ECU to relearn and adapt to the adjustments better, plus it clears out any old CELs.
Good Luck
