misfire on cylinder #1
#1
![Default](/forum/images/icons/icon1.gif)
Ok guys time to pick your brains.....
03 x type was running fine until a few days ago. Was making a right turn and the car started to misfire. I just changed all the gaskets ,plugs, and coils just about 6 months ago. I just checked the plugs and they look fine. I swapped coils but have not checked it on the reader yet. I will do that tomorrow when I get a chance. Anyone have any ideas what else it could be....I need to replace the valve cover gaskets as there was oil in the well but not in #1,#3,#5. It was in #2 and #4.#6 was clean
Thanks in advance,
The Dr!

Could be the injector has gone bad. Same thing happened to a another car of mine recently. There are a rather large number of causes of misfires - grounded wiring, bad coils, bad plugs, vacuum leaks, damaged gaskets, etc.
Is the check engine light on? If so, have you read the codes? If you have, then please list them as that'll give us something to go on.

Dr Dome, I would pull the coil off and see if there is any oil in the well. Odds are, you are going to find some in there. After that, I would try swapping the coils for #1 and #3 cylinders. If the misfire moves, then that confirms a coil has gone bad (just because it is new, does not mean it can't fail). If the problem remains with #1 cylinder, then you are most likely looking at a bad fuel injector.
