my 03 marauder i had since new and i still love this car, i noticed she is starting to run sluggish when im in traffic in town, then give it a little gas and when i have to slow down again it does it again. i hit it to rev it up then its ok. i hope im making sense, like if im driving in a sub divisionat low speed it really run sluggish.:bows: any sugestions.

Might be a dirty filter, Try cleaning the MAF with MAF specific cleaner, Bad gas

It sounds like the throttle position Sensor, or the Idle Control Sensor
both of these can have an effect on the idle and response when you hit the gas.....You need a code reader to see if its putting out any error codes...

I think advanced auto parts will scan it for you @ no charge if you dont know someone with a scanner.......Good luck to you, hope this helps you out.

Spark plugs?

Fuel filter?

How many miles on the car? What maintenance have you performed recently, air filter, fuel filter spark plugs etc...?
