My car is hesitating real bad and I took it to get the check engine light checked out. It turned out to be a misfire on cylinders 1,3, and 4. I'm trying to fix the problem bnut have no clue what cyliners are 1,3, and 4. Does anyone have a diagram or a picture that shows which is which?

so I have the 2003 Acura TL and diagnostic says misfire. how do we know if it's an actual plug or a coil pack?
Mine is showing cylinder 2 misfire.

so it would be cylinder bank 2 against the firewall regardless of the firing order right?



firewall
123
456
front of car

so change the plug or the coil pack or both?

Pharmacist, The number two cylinder is the middle one next to the firewall. A misfire can be something else (fuel injector) but you hit the most common causes. I would pull the coil on plug, and examine it closely and see if you can see any pinholes or carbon traces that indicate a pinhole. I would also pull the plug and check the condition. You can find pictures of how a plug should look online. I think most people would replace the plug first. You can change the coil pack and the plug (if it is not obviously bad) with another cylinder, I would change it with one of the front three cylinders. Run the car and see if the misfire follows the plug and coil. If it follows you can then do one at a time to narrow it to the cause. If the misfire is still for cylinder two I would then look at the fuel injectors. if you are using an OBDII reader is the Short Term Fuel reading very different from the long term fuel reading?

Decided to add a nice picture since this thread has been looked at many times.
