Air flow meter

[Jzza4]

Thanks again everyone for the replies.

Today, my car nearly stalled when I stopped at a light. This has occurred once before when getting off the highway, my car nearly stalled when stopping. Any ideas?

I looked at my MAF, which looked clean. When I bought the car, the valve cover gasket needed to be replaced, which seemed to be the reason there was some oil in the air filter housing. I Cleaned the plastic hose connecting the MAF to the throttle(?). I tried running the engine witout the sensor connected, which didn't make much of a difference.

Idle control valve, crankshaft position sensor, camshaft position sensor are next on the list

The stomp test resulted in code 1215 (MAF).

Should I try cleaning it with carb cleaner before buying a new unit? Must I remove the MAF when using the cleaner? or do I open the air filter and spray inside to the MAF?


Chrome wheel cleaner products....Anyone?

Remove it to clean it. make sure your air filter has no holes or tears in it while you are in there.

I would probably guess that your throttle position sensor has a flat spot in it. If it happens only on the freeway - I would guess a lot of highway miles with steady pedal pressure.

You would really need to look at the data stream off the MAF to determine if it was good or not. This is where a shop with spares and diagnostic equipment comes in real handy.
