I have a 2002 RSX Base, Everything is stock.
It seems to have some low rpm drivability issues I need some help with.
When driveing and clutch is pushed in the idle falls to about 800RPM istantly, then comes back to about 1500 somtimes 2000 for a few moments then slowly falls. Sometimes it will bounce up and down 1K RPM a little bit. Idle is in the right spot at around 800RPM There are no vaccum leaks that I can tell.
I removed the throttle body, cleaned the IAC, No check engine light, have reset the ECU, Checked throttle cable tension. Im at a loss! Help guys

seems like you are running super duper lean.

make sure that your ecu is set to stock. Are you 100% positive thaat nothing is modded? your ecu might be sending a message to your engine that makes your engine have the wrong air-fuel mixture. double check that your engine is stock (only thing i can think of is maybe a different degree cam? dunno, not thinking clearly =P), if it is stock, reset the ecu again and make sure it is the stock map.

Things should get cleared up by then. good luck with it.

 

bleed coolant?

 

I did not bleed coolant, my car is 100% stock with no check engine lights, very well maintained. I will try bleeding coolant

 

I found out its a bad IAC valve.
Anyone got a working one they would like to sell??
