1992 Pontiac Bonniville SSEI runs but has a miss to it... checked all plugs and wires and they are good... used a spark tester as well and there is juice from coils to all 6 plugs great spark.... when she hits overdrive is shutters pretty good as well
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 soconfuse! I am very knowledgeable with all GM cars and trucks and this is honestly a first!
pleasehelp!
