my 00 max with 57k on it started up and ran on only 5 cylinders. both times when I went to lunch from work. The first time it fixed itself after about 5 miles. the second time it would not get right. But it was ok when I went home from work. Two times now. I had better figure out what is happining. Is it time for a tune up? or some fuel treatment? anybody had this happen to them? Help

 

how do u know it ran on 5 cylinders?? id say its your coils, time for some updated coils
