My car just two days ago started acting funny. Every once in a while when i have a steady low rpm drive going(like in cruise contorl) in primarily 2nd or 3rd gear my car will start to studder and rock back in forth sometimes rather violently. Just today my check engine light came on. At first i thought i might have water in my gas but i have filled it with a tank and a half and it still does it. The only thing i can think of is something to do with the fuel line. Anyone have similar problems or any of you car geniuses know whats going on? Thanx for the help guys!

The first thing you should do is have the DTC pulled with a OBDII reader. That will help narrow down the problem. Have the code pulled and let us know what it is.

Possibly:

Spark plugs.

Plug wires.

Coil pack.

Fuel pump.

Fuel filter.

Injector(s).

Injector pressure sensor.

Or maybe it just needs a good fuel system cleaner (I recommend BG 44K).


Does it do this as bad with a full tank as opposed to an empty one? Does it stop doing it above a certain RPM?
