Test #2, New spark plug wires, look at the plugs did not look good, gap to 40 ran good but I went ahead put in some new spark plugs MotorCraft AGSF32PPM thay do not make them any more I put in some replacement MotorCraft plug std gap 54, run good for a week after that
runing bad agan. Test #3, So today I completely clean my IMRC and put in some new pulgs, AUTOLITE APP764 gap to 40 so far so good we will see in a couple weeks if she is still runing good I think I have a weak coil.


Week 11, still running great! I think this will be my last post on this one, unless it starts running bad agan. knock on wood

Last week my car started running bad agan, boy was I piss off! So today I took the ignition off the car and tested my coils, spark plug wires, look at the plugs, my coils are in spec,wires ok, plugs good, so I cleaned all the parts with carb cleaner, after that with brake cleaner, then I put some ignition protector on my wires and coil, after that I put some dielectric compound on all connectors, made suer all terminals fit tight, after I install all the parts I went for a test drivr, for now she running great, we will see how long it last this time.
