Balast resistor or no?

The 0.5 ohm ballast and the 1.4 ohm coil should work with the stock ECU. I agree that it is likely a bad coil.

I bought a masterpro coil a at Oreilly because that is all they had. It lasted about a week. I took it back & ordered a Standard Ignition coil. When it came in, it was the exact same coil. Chinese crap is everywhere, even name brands.
