Engine ECU

Same issues with two different MAF. The old MAF I think was damaged from oil leaking past the AOS which was replaced last year.

I think what happened to my DME is it got damaged by water from the leaking coolant overflow tank. The inside of my trunk was like a sauna when summer hit.

Condensation on the trunk lid and I think the humidity in there probably damaged the MAF. It was like locking the MAF in a steam box. And coincidentally the problems all started when it got really hot here last summer with temperatures in the 90s. But the car never overheated or anything.

Anyway this is all just conjecture on my part it's in the hands of my shop now they have the right diagnostic systems and experience I think they can fix it.

@Bootlegger: Surging idle, poor throttle response, car would die occasionally if the tank was less than half full, check engine light on.

Shop also mentioned possible problems with fuel tank breather system and or fuel pump

@Deadeye:I looked into them and they seem like a great option for the future they reprogram your DME so it is a plug-and-play replacement

Just a thought.....as a person who drives 50 miles to work each day (100 miles round trip), a 30 mile jaunt to the dealer seems like a piece of cake.

It's not the distance. The service there is extremely bad. I will never set foot there again unless forced.
