I have an 02 suburban and was driving it and it developed a very bad miss had it hooked up on a computer and it said misfire on 1 and 3 cyl ran a compression test on # 3 cyl and the guage did not move at all i have seen a blown head gasket before but it would build a little pressure and gradually drop down this thing did not move at all. I am new to this site and any info would be greatly appreciated
