Answerdid you check your fuel filter? AnswerIf the problem is still there after you have replaced your fuel filter, check your fuel pump pressure; you may have abad fuel pump. Mark

------

If your fuel pump is bad, the whole car dies. There's really no in between there. You can have a whole slew of problems...

- Bad O2 sensor.

- Faulty / Bad Spark Plugs / wires

- Coil pack (maybe it had more than 1 coil, and they replaced wrong one or not all)

- Vacuum Hose leak

- Catalytic Converter is clogged

- Clogged / Bad Fuel Filter

If you have a "Check Engine" light on, and your car was made after '94 (meaning, '95 and up), try having the codes run at a local auto parts store. Some do it for free, or if money's not an issue, just take it to a dealership and have them do a diagnostic. Generally, they'll charge you anywhere between $40 - $120, but they will tell you EXACTLY what is wrong, as well as ANYTHING else (even little things). The problem with cars, besides being expensive pieces of crap (regardless of which brand now and days), is that anything going wrong could be a whole bunch of things.
