Every now and then the engine will do a power surge. It happens mainly when i am at a stop light and car has warmed up. Would this be a fuel pump related problem or something with the air control?

Hi Kitty, and welcome back:

If the idle is erratic, I have a couple ideas but my first suspect is an engine vacuum leak. Try this test first and let me know the results.

Let me know what you find or if you have other questions.

Take care,
Joe
