My whole car vibrates at idle, but when the engine gets up to about 1500 RPM everything stops vibrating, and when shifting into second while accelerating hard, the eninge bogs then it seems like sumthing catchs and the engine accelerates correctly. any ideas??

Clean or take out the AIV.. were does it idle at?

 

extreamly low i think right round 500

 

I feel like its you AIV.. mine was the same way

 

umm newb question what is an AIV?

 

Air idle valve

 

man theres a shitload of people with the idling at 500rpm thing... you, me (not always), a pt cruiser..

ive replaced everything but TPS/air control shit..

 

Can you bring me the car on Thursday or Friday? I dont trouble shoot the factory ECU setups too well but if its something mechanical i could find it. $20 an hour with $20 minimum.

 

Do you know how to adjust your idle? My friend has an altima with a KA in it and it did sort of the same thing. He adjusted the idle up to about 900 rpms and it didn't vibrate anymore.
