This answer is in response to your most recent question.
Yes, it does stumble but not as bad.
Also, the exhaust smells like eggs when the CEL is on and it only bogs down within 600-1.5/2k RPM, higher RPM is fine.
The answer below is in response to your previous question.
If I restart the vehicle it runs fine and the CEL will go away after 1 or 2 driving cycles.
So basically, when I park the car, pop the hood and turn it on (and the CEL is gone) it runs perfectly until I unplug the MAF sensor, at which time it'll bog down and rough idle - no misfire codes, should I be waiting a certain amount of time for them to appear?
Additionally, If I were to unplug the MAF sensor while the CEL is present (for example after the car starts to act up), nothing changes.
- When the car runs good, unplugging the MAF causes issues
- When the car runs bad (which is what the issue is), unplugging the MAF produces no change to Idle or revving
It seems like when the CEL is present, the ECU is ignoring the MAF?
Any other ideas? It appears the voltage is not the only cause of this P code.
I'm basically trying to eliminate all possible factors that could cause this code.
I do have STAR DAS, can you tell me how to run codes with it, will that data help?
