Hi Michael,

I need some more info, is the engine running rough, misfiring etc?

Rpm going up and down really means nothing, every car does that.

CAR ALSO HAS A P0011 ENGIN CODE
Expert:  Gary replied 4 months ago.

Hi Michael,

The P0011 is important to look at.

Could also be timing chain related.

I would also clean the throttle body.

How many miles on your engine now?

How long, and miles since last oil change?
