wENT OUT LAST NIGHT AND STARTED PUSHING THE CAR A LITTLE not a lot.but I think I messed something up because my CE light came on saying I have a 4th cylinder misfire and now it spudders when I drove home. Spark plugs were a tad white so I was probably too lean. Do you think its major. There wasn't any smoking just sputtering on startup and throttle/idle.

put new plugs in it first and then let us know what happens!!!

Injector could be clogged or just went bad.

My thoughts exactly. How many miles are on your car? Have you ever had a fuel injector/system service? We reccomend every 30-50,000 miles depending on the vehicle.

Also, what condition is the fuel filter in?

fuel system is so fresh and so clean but I do believe I blew the head gasket I should have it fixed by next week

I recently upgraded to big 16g and I've been tuning for more boost but basic stuttering

Check for oil in the coolant.
Compression test.

BTW I dont believe a blown HG would cause only one cylinder to go out.

It could if the gasket happened to be cracked just around cylinder #4.

My cyl 4 misfire was the coilpack. Test the primary and secondary resistance per the manual.

Where are the coil connectors on a 1g?
