Question about 1999 Ford Crown Victoria
I have checked all the plugs and they are fairly new (Most likely replaced this year). The wires look fine, but I'm not sure how to test the ignition coils. It seems to me that one or more coils are not firing correctly. Anyone know how to test these? Also, when it starts to misfire at normal cruising speed, I'll step on the gas pedal a little and it helps to smooth it out. Taking the car out of overdrive sometimes helps a bit, (probably by increasing the rpms), but not always. Usually stepping on the gas pedal is the only way to smooth out.
Try using a friction modifier in your trans fluid. I know this sounds crazy but I have done this before for people who come into my shop complaining that at 40-45 mph the car shakes or chuggs. I tell them to do a complete trans fluid change with our T-Tech trans machine and put in the friction modifier and it has worked any of times. You can get the friction modifier from Ford for about $10. As far as checking spark the only way to do this is with a spark checker while running.
