Hard starting and running rough?

Hi,

I'm not sure which thread you are referring to. Can you explain what is happening? I'll try my best to help.

Let me know.

So, whenever I start the car, it idles very rough and the engine stalls. No 'Check Engine Light' is present at any time. I need to feather or depress the gas pedal to keep it from stalling. If I get the engine to somewhat warm up, then it idles very rough. The thing that happened was that I didn’t change the air filter for a while. One day I came from work, and it was idling rough. I pulled the air filter and the filter had disintegrated so some particles from the air filter went inside the intake manifold. It had a code which was the air mass flow sensor, and I replaced it but it’s still doing the same thing. It was running fine before this happened.

Hi,

Based on that information, I would recommend cleaning the throttle body. Also, check to make sure there are no vacuum leaks. Here are two links that explain how to perform both:

Let me know if that helps.
