Hi guys, i have problems with a cop, but i don't know which one, and i see other people on here having problems with them. Is there any way to test them? can a ford dealer test them?
thanks guys.
if you have old spark plugs, that is the first thing to change. if the miss gets bad enough, the computer will give a code telling you which cylinder is the problme. you can then replace the COP, or put it on another cylinder and see if the code moves to it. dont know if FORD can test the COP or not, dont think Auto Zone can do it.
Ford dealers CAN test COPs.
I used to do drivability at a dealer and I used a piece of equipment called WDS to do a stress test on Coil packs.
Normally if the COP goes out,you WILL get a misfire code.
If you dont get a code,and have a misfire,more than likely the COP boot is got a pin hole in it.
thanks guys, i have changed all the plugs and boots, but no help. i'm gonna try testing resistance to see if there is a difference in one than the others, if that doesn't work i'm goin to the dealer
