this was not even the problemi checked the coils with ohm meter and it said they were good wrong. i took all the plugs out and one by one i put them in the wires and laid the wire with the plug in it and then turned the car over and the leading coils were bad no spark at all. the trailing coils are working great so i bought some coils and now i wait for them to get here and i hope this fixes my problem

I hope it fixes your problem also, but your leading coils check may have been invalid. You only have one leading coil, even though it has 2 plug towers. In order to check it, BOTH spark plugs must be grounded to complete the circuit. That means you can check either plug as long as the other plug is installed and/or grounded with the other plug wire plugged on. Otherwise, there is no path between the 2 leading plug towers, and there can be no spark even if there is no malfunction. Good luck!
