About a month ago, my car would not start. Long story short, the fuel pump was bad. Got it fixed. After It was fixed the CEL was on. At first the code was P0101. Told the person who did the fuel pump was it was and he put a MAF Sensor on. Car instantly ran better. Went to the gas station. When I started the car ago the CEL was off, meaning the computer reset the code. On the way home the car stalled in traffic. Waited a few minutes and it started and got me to a parking lot. Called up my "mechanic" and was told to unplug the maf sensor. Car started without a problem and got me home. I put the old sensor back on which was clearly bad as it was crack clear across the top. So I went out and got a sensor. Car ran better for about 20 minutes then did the same thing the 1st replacement did. Advanced auto swapped out the part for a new one. Also told me the code is now P0102 - low circuit input. I don't want to put this new one on if something else is going to make it go bad again.
Checked the connections to the maf and everything looks okay.(Advanced told me my connection was bad) Never had a problem before the fuel pump went bad. Ugh.
Other little things:
When coasting to a stop on a highway exit, car rpms surge and lights dim sometimes at night.
Sometimes idle is fine, others the rpms surge a little.
What can I do? Don't have much money too throw around. Then again, What broke college kid does? I'm not to familiar with the engine, although I can do small things like brakes and an oil change.
