Hi everyone,
I have an issue with my 2004 Explorer. It has a miss when at a stop light,the RPM drops a little and it acts like it wants to stall but doesn't. A friend of mine who is a mechanic told me to replace the wires which I did but still has a miss at idle and at a light. He said #5 was dropping a little bit. Could it be the coil? I've tried new fuel filter,air filter and now new plug wires. Cleaned MAF cleaned throttle body. Checked some of the ground points. No check engine lights on. Thanks.
 












It showed no codes Wednesday. New plugs were put in 4000 miles ago. It doesn't do it all the time. Just wondering if it could be coil. Don't really know how to test it either.
