I'm experiencing a Cylinder 3 misfire. I've changed out all of the plugs and coilpacks and this issue still hasn't gone away. I also cleaned the MAF as well as the air filter also. Still throwing the code. Has anyone else experienced this, and if you have how did you resolve the issue???

 

Remove the fuel pump relay from the IPDM, crank motor and run until it stalls, remove the suspect spark plug, plug it back into the coil pack and hold it with a leather gloved hand about 1/4" away (measured from teh ground strap of the spark plug) from the intake manifold while someone else cranks the motor and you visually observe spark. Compare with a second spark plug, compare against a different coil pack. If there is a weak spark or NO SPARK you will see the difference when compared to another cylinder. You might have a damaged wire, wiring harness, another bad coil pack, etc.

 

Might want to check #3 fuel injector as well, while you are messing around in that area.
