I have a crazy missfire going on. Had the codes run (which I don't completley trust) and it says missfire on number 6. The first thing I did was switch the coil pack and had the codes ran again... still number 6. That rules out the coil pack. I also stuck another injector in six (not a new one) and still the same problem.
When I first start the car the miss is not near as bad for about 30 seconds. Once the car starts to warm up, there it is. Also, at times during acceleration the miss is not there, but when it levels out the miss comes back. I have changed vacuum lines, egr, coil packs, plugs and injector on this one cylinder.
The car does have a slight tic on the driver side. I tried to tell where it is comming from by putting a rod on the valve cover and puttting it to my ear. Does not sound like the numb six cylinder. Could it be a broken valve spring or a bad cam lobe??? I would think the miss would be more consistant. Have not pulled a vacuum test yet or compression test. Thats today. Also have not pulled the valve cover off the driver side yet.
The car is a 97 with 180 on the clock.
