I would check the coil packs..it can make the car jerk and feel like its slipping if those go bad.

Have you checked your CAI for air leaks? your RPM's will run up and sometimes bounce with a leak. Take some starting fluid and spray it around when running. if your RPM's shoot up you found the leak.

Like, a leak after the MAF? Where the Maf tells the engine there is this much air coming in, but only some of it is making it to the intake? Makes sense, but then again, how does it relate to working fine for 10 min, then messingup? Also, wouldtn a gap or hole or whatever also allow air in? its just sucking in unfiltered air, after the MAF.

Whats starting fluid?

the stock COP connection to the plug is bad, the new ends are worth the $ alone. you might have a hole in the rubber boot.

I kept having a stuttering problem, but I could tell it was the engine not the tranny. I have a coil pack going bad and it keeps blowing out the spark plugs. Then it stops for about 3 weeks and then starts up agian. Just replace the plug and go on. After I get my gears in, it'll be a new coil pack for me!

Problem like mine? Where the car would have to heat up a bit before messing up? Now that i think of it, i did mess up the screw that holds the coil pack in, on one plug. The one all the way in the front of the drivers side. I somehow cross threaded it, and the screw wont go in all the way. Theres a little bit of play in it, so i tried securing it by putting washers around the screw, till it held tight. Still a little wiggly.

Maybe thats it?
