Well my car has been running like crap lately,

It will, when the engine is cold, stumble and backfire when ever you shift gears or get out of the throttle then back in. It went away when it warmed up all the way. It has a steady misfire at part throttle operation.

I pulled codes today

KOEO ( Key on Engine Off)

33 - EGR or Canister problem.
66 - NO MAF Signal ??? think that may have been stored, i disconected the MAF with the car on recently.

KOER ( Key On Engine Running )

21 - Coolant temp out of specfied range - I didnt let the car warm up to past 180.

44 - Air Management System

Can anyone elaborate on these please.

Mike

Unplug the vacuum line going to the EGR and see if the engine runs better. I had this problem on my pickup (302 engine). Your EGR may be clogged or stuck open.
