ok so this morning i turned on my RSX and surprisingly it idled very low. around 300-400 rpms. then i drove it and it felt a little hesitant. after that, it started to stall at every dead stop. the only way i can go is if i dont make a full stop because my car wouldnt idle. no check engine light and everything is hooked up properly. then at one point i got mad. i floored it on 1st gear and tada... problem fixed. no more stalling.. anybody got any idea?

 

spark plugs.......

 

maybe this will help?

i had similar effects, but also had high idle at times- lurching when trying to creep in first gear.
i didn't have a check engine light at first, but mine was throwing the codes after a week of driving like that...

it was my rotory control valve- as the dealer calls it (aka. Idle Control Valve- ICV... AKA- Idle Air Control Valve- IACV)
try cleaning it first- there are DIY's on it somewhere on the net.

 

It could also be your Tps. It could be bad

 

bad TPS sensors usually throw a check engine light. its probably still its acceptable range of voltage. Try your plugs and clean out ur ICV. Then reset ur ECU
