Code 34???
If the MAF sensor was bad would it start and run poorly with it unpluged or would it still start then die? Just replaced the relays (not to long ago) behind the battery.

Usually you can tap the MAF with a screwdriver and disconnect it and the engine will run slightly better, though not always.
Sounds like its time to replace it.

Well, so far its not the MAF sensor nor is it the burn-off relay. Still trying to locate the power relay. If this isn't it would there be any other sensors that will cause this particular problem? :banghead:

Have you cleaned the TB and IAC?
How did you determine that the MAF was still good?
The two relays sitting behind the batt are the power and burnoff relays, if you replaced those recently i would eliminate them, although a bad MAF could end up killing them and vice versa.
Otherwise its a connection, or the ECM.

Well, just replaced both relays behind the battery along with the MAF sensor. Now no code 34 but it still starts up and then dies unless giving it gas then it runs. My next step will be to remove the ECM and replace it since it has a lifetime warranty. Also the IAC and the throttle body were cleaned last month when i was having the same problems. :banghead:
