Try cleaning your MAF sensor.

Thanks for the quick response aldive! Any thoughts on what causes this or what might fix it?

edit: thanks folks.....Its got a rough idle/stall/surge problem....I have cleaned the IAC and bought a new TPS today. The codes I got from AdvanceAuto earlier today.

Read the link I posted, it should help you.

after reading that article, I would say the problems I'm having may or may not be from those codes, I will replace the TPS tomorrow and clean the MAF and see how she goes.

Good luck and keep us posted.

No luck with the TPS...no change. I am afraid it might be manifold orings. Has anyone had this done and paid for it? If so how much? There is 80k on it so no recall
