Service engine soon light


Sorry, we are not "psychics" on this site. You need to diagnose the service engine soon light to find out which of the MANY circuits and systems monitored by your onboard computer is malfunctioning.

It sputters when i start to press gas going up a hill or when preparing to pass a vehicle?


It may just need a new fuel filter. Or a change of spark plugs, wires and any other wear items.

Is your service engine soon light lit up?

If it is then scan your computer for trouble codes and repost the codes.

Good Luck.

Describe your service engine soon light blinking


you have a missfire that is why the light blinks, it also will have a trouble code stored showing which cylinder is causing the problem, but this sounds like a plug or plug wire issue.
