Well I was driving to town t get a bite to eat and about half way there my car suddenly lost alot of power and developed a bad shudder. It wouldn't accelerate and struggled under load. It drove like it was not firing on all cylinders and when idling I could feel it miss every few seconds.

I made it to town and decided to swing by Auto Zone and have my codes read. They came up with 2:
P0110 - Intake Air Temperature circuit fault
P0100 - Mass Air Flow circuit fault

Now correct me if I am wrong but usually when the MAF goes bad you cannot rev past 2500rpm so I don't think that is the issue.
And I was under the impression that the IAT was only used until the engine comes to operating temperature so why would that affect the car when it was already warmed up?


Anyone who can help will be greatly appreciated so thanks in advance.

Actually as it turns out those codes had nothing to do with the problem. Water had gotten into the spark plug plungers causing the spark to ground onto the case and the codes came from when I had my intake off to replace the front pulley and had to move the car.
Sorry for the useless thread. My car is running great now.
