My tracker appears to be missing. Have had the plugs and coils replaced twice in past two months. My mechanic put it on the diagnostic computer and no codes came up. Replaced the fuel filter also. It doesn't do it all the time. Sometimes it runs awesome for 40 miles or more and sometimes it misses almost constantly when I drive 1 mile to the store. My mechanic is at a loss

Did he do a compression test? Did he check fuel pressure? Did he check spark?

One of these is the clue to the failure. If he cannot find it, take it somewhere else to have it repaired
