I have a motor out of a 96 chevy 3/4 ton. 5.7 vortec. Everything is stock except I put in a 99 Tahoe computer. Cylinders 1 and 2 are missfiring. Have spark, fuel pressure is fine, and holds after turning key off. All plug wires are in correct locations. All other cylinders seem to be doing what they are supposed to. While running, I pull 1 and 2 off the distributor and no change in how it runs. Also engine ran perfect before we pulled it.
Thanks
Daniel
