Well like it says.... I have a random misfire. I took it in to my buddies shop and we hooked it up to his diagnostic machine and it is picking up a missfire on all cylinders at an idle. At an idle you can tell but once I get over 1500 rpm it seems to go away but the reader it telling us that shes still misfiring. We did a vacume leak test and a compression test and everything looks good. So im looking for some ideas. Can one bad injector cause a random misfire accross the board???
