I just installed an ATI into a friends 96 stock stang. It worked great when he left my garage and on his way home it started sputtering/missing when he accelerates above 2000-2500. So the first thing we did is check the plugs AGAIN and the wires. We even swaped wires AND took the blower out of the loop and it sitll does it. The car WITHOUT the blower doesnt want to run right after about 2000rpm's. We even disconected the inline pump and installed his aftermarket chip that was burned for the combinaton. The car STILL ran like it was misfiring or studdering under SLIGHT acceleration. When it is cold the problem is not there....but as soon as it is running and temp is normal operation, it sputters/misses/misfires. At one time we even made the engine check light come on at 1 sec intervals indicating a missfire. Now here is my question. the only thin that we have left to turn back to the original start point before the s/c install is the NEW plugs. Has anyone ever run into this problem before? Thought it was detonating but it does it now WITHOUT the blower even running. Any input, cause we spent 15 hours and he spent 4500 on the products.
