Hi all, My engine does not have a consistent and steady idle. It slightly fluctuates up and down while sitting at idle. Anybody know what causes this ? Thanks

 

I'm guessing it's the throttle position sensor. For a quick fix you could take out the screw a bit, but that won't really fix any actual problem that there is with it, it will only make it so that you can live with the car. I would suggest getting a new throttle position sensor. Also, I hear that leaky vaccum lines can cause funny idle.

 

Dude!

Dont change the TPS till you verify its good!

Download the FSM, the steps are in there.

my car does the same thing no and then. i just had the TPS re-adjusted and it still does it. plus my "check engine" light came on today... does it mean that i need to replace the TPS entirely?

 

What code did you get?
