Installed Hypertech coil and got CHECK ENGINE light,,,,
I am confused,all wires were attached and well plugged in?
Any precedent to this,,,
Is there a way to test my coil off the car?
however you need to make sure that you have the right coil for your year car (obd2 or obd1)i got an msd coil for my 95 formula and had no problems fwiw.
