Hi there.

I can probably help you, but first I'll need to get those misfire code numbers from you; can you post that information?

OK. There are several different misfire codes that would point to different circuits and components, that's why it's important to know the exact numbers. Any major auto parts retailers will retrieve the codes for you free of charge. Can you get them that way?

Hey there this is another tech. The charges will be refunded if by mistake. This will be done by customer service. No need to worry they will make sure you get any money back that was incorrectly charged. I want to help fix your concern. With this problem the first thing you want to do is replace the spark plugs on all of the 6 cylinders. If the issue is still there you are looking at a weak coil that is producing the spark to the spark plugs. The coils in my experience normally last around 100k but after that you need to replace them. I would order a complete set from ebay as they will cost about the same as 1 from the local parts store. Yes the ebay ones are cheaper in quality but they normally last as long as the good OEM ones in my experience. If you have any questions do not hesistate to ask. Thanks Charlie!
