Changed plugs, wires, ignition coils, and modual, MAP sensor, MAF sensor, changed Injectors everything! I put a spark tester in between the plug and the wire and good spark all around still says number 5 cly! When u drive it its great all the way up until overdrive, once in it shakes real good till about 65 then u can barly notice it I am SO CONFUSED! I am VERY knowledgeable with ALL GM cars and trucks and this is honestly a first!
