at idle my engine sputters, i can feel it in my exhaust...and i can hear it loud and clear...perhaps the engine is running lean? ANother thing....just for haha's i had the motor running, operating temperature, idling, i unplugged the o2 sensor and absolutely nothing happened....no idle change, no misfires when i revved the engine..nothing...could that be my problem? thanks..

 

make sure your iac valve if functioning properly.

 

where is that located?.....would a vaccum diagram be in my manual?

 

where is IAC valve located? i need to clean mine too, my idle is too low, anybody has a picture of it or a diagram where to find this? can i used WD40 to clean this?


thanks

 

it was my plugs....bosch suck!
