QUick trip up the street to Advanced Auto parts, New MAF, (138.99) Installed it in the parking lot, followed by 30 min test drive. No more stalling, surging or bucking. Im calling this one fixed.
Good to hear you fixed it.

Thanks for the ride in the thred!

I see the parts stores are kinda proud of that part! 90 dollar core charge!

Would like to see whats inside that thing, thay are rebuilding them.

During eng operation they really dont get hot. and they do have fresh air passing through to cool. I was thinking solder joints. The ice is sorta a "fire and ice" diagnostics.

I disconnected my MAF to test it and my stalling problem stopped. However, Now it appears to be running a little hot. Is that normal?

Unplugging the MAF wont effect temp. By hot what are your saying for a temp?

yeah i noticed that when my vehicle is at a stop the temp will rise a little higher than normal. I am not sure if that would have something to do with it. I just replaced the thermostat and the air cooler elbows so I am not sure what it could be.

As long as it'* not getting real hot, it'* normal. When you stop less air is going threw the radiator.

That'* why you can find Freeze-It or component cooler aerosol cans at your local electronics store. The flip side is to use a heat gun or a soldering iron (for individual components) to find the weak ones.
