Well, where do I begin... About a month ago I took my car out and noticed a fairly significant problem. my car was running fine at anything under WOT but as soon as I went WOT it felt like the motor was not firing on all cylinders and the car started to rock back and forth while I very slowly accelerated. I thought this might be attributed to knock retard so I decided to do a DE-CARB procedure. I pulled the plugs and they looked a little beat up so I got new ones, then I performed the procedure. the car is still exhibiting the same symptoms as before and I am lost. My car has not thrown any codes since this started and I have only seen one check engine light that did not go away until I disconnected the battery. My fuel pressure stays pegged at 60psi and my oil pressure is 30 at idle and is maxing out at 59 at WOT. Coolant temp is normal, oil temp is normal and I can rev to 6,000 RPM while sitting still or in neutral with no problems. I don't know where to look next. Also, I would prefer not to take it to a dealer because I have voided the warranty and it isn't exactly street legal.

Thanks in advance for all your help,

The latest mod I did was the Cartek Stage 2 heads and cam and it has been on the car for about 4,000-4,500 miles. All other mods were completed prior to the heads and cam. My car has about 28,000 miles on it now.

Thanks!

I had a 2000 Z28 before I got my vette.
I had something similiar to what your describing and it turned out to be a bad spark plug wire!

Good luck!
