Read it with a good scan tool first otherwise its a shot in the dark.

was a misfire on cylinder #1.

 

Coil Pack connection wire most of the time when its just one cylinder, then check the plug itself. Then Change out the coil pack.

 

i had plugs and wires done within 6 months ago. Maybe a fuel injector is dirty?

 

sorry about that i sent that message before I saw yours show up

 

Check the torque on the plugs, make sure there isn't gobs of anti seize or dielectric on everything.

If it started right after fueling up I would caution a guess to the quality of fuel. Are you sure you didn't fill up with E85?

 

No problem. Did you ever scan it? Also make sure the wire and plugs are tight and snapped in all the way, as well as the spark plugs. They can work themselves out. Also with a good scan it would tell you if the injector is firing. A quick way to check that is to unplug that wire harness plug to it.

 

I always use E92.

 

ECS I did have it scanned, misfire cylinder #1.

What happens when evap leak occurs? (fuel cap not sealed) SES light comes on.

 

Ill check the wires tomorrow and see what I can find.
