If your engine also seems to be starved for air or fuel on acceleration from time to time, it may be the air control valve seal. I'm not sure of the technical name for it, but on the upper air manifold you should see 2 round black plastic covers with wires going into both. They will be held in place by 2 screws. I had a similar problem, and after spending $11 at the dealer I picked up 2 seals. They are round and green in color. The screws on mine were loose and the engine sounded like it was sucking air. 10 minutes later (after replacing the seals) all lights went away and it's been fine ever since. I did not have to remove any additional parts to get to the seals. Give a listen at engine idle. If you here a high pitched sucking sound by those covers, it's most likely the issue. A simply fix. Hope this helps!

 

I'll look into that, I'll keep you posted.

 

I need to get the JTIS to find out exactly where it's at. Having issues locating it, not sure exactly what I'm looking for even if it was right there starring at me. LOL!

 

anybody?

 

I found out if i accelerate fast between 20mph and 30mph it starts changing gears in a weird way where the car kind of pulls lets go the pulls again.

But If i don't accelerate fast and go normally then it switches gears smoothly.
