1998 Chevy 1500 5.7. Experiencing a miss. Misses at idle but quiet, misses at speed but accompanied by a noise that sounds like popcorn being popped in the muffler.
I have replace the Distributor cap and rotor, plugs and wires and finally the entire distributor. ""Didn't fix it""... Replaced Injection spider. ""Didn't fix it"".
Please Help!!!
