Hello yet again! I have some new information on the 96 z28... The egr seems to be the culprit, I unplugged the vacuum line and nothing it idled slightly worse. but I'm not sure that's the only issue. It has a deep knock type sound from the lower engine, compression issue? Also has a horrible exaust leak if that has anything to due with the issue. I have a couple new videos, in cabin and out. Also have a fun video of a good friend recording while I'm driving the camaro, he drives a 97 mustang gt with the 03 gt motor. Reaction=priceless. Thanks again everyone for the input on all of my other threads, and I'm sorry for annoying everyone with these questions! 96 Lt1 10-75 with missfire. - YouTube also the opti, and the sparks are brand new wire looked good. http://youtu.be/EOOnHetcNxY
