Guest zcars74 Posted April 18, 2002 Share Posted April 18, 2002 How would you check to see if you have a bad EI control module??? It's on a 260z. I have a msd blaster coil and new plug wires. When i'm taking off it jerks but once I get to 3000rpms it stops. So as you can imagine if i'm in 4th and go below 60mph the jerking gets really bad. This problem just came out of the blue. It ran cherry the day before then I got in to start it the next morning and it doing this. I had to bypass the ballist resistor so the coil would be getting the full 12 volts that it needs to recharge. i've had the coil for about 2 months now. I'm stumped somebody please help.
