taylo496 Posted January 17, 2013 Report Share Posted January 17, 2013 Hello, I have a 2000 Deville (Northstart) when I begin to step on the gas it like hesitate to go. It also has a misfire. I put the car on the machine and it said it was just a spark plug. But when I got my oil change there was oil on the engine. Could it be my coils also. Would that case it to stall and misfire. Please help. Thanks Link to comment Share on other sites More sharing options...
Logan Posted January 17, 2013 Report Share Posted January 17, 2013 On the 2000, using a typical aftermarket scan tool or the IPC self diagnostics system will only display a 'random misfire' P0300 code. There are no codes P0301-308 on a 2000 MY. Using the GM Tech2 scan tool will clearly display which cylinder is misfiring. Problem can be plug, boot, or coil bank. Or...something worse. Picture of a GM Tech2 showing a obvious misfire on cylinder #6.
