Question

Car ran great then, I tried hooking up an autometer tach, Now when you start the car it lopes and surges, no vaccum lines are off. I have a accel ignition on the car, (fuse is good on ignition box ) and so are all the other fuses, And its not throwing a code.... Whats the odds of the ignition module being bad??

Welcome Kws95cameroz28. I have one question. Have you removed the tach wire and tried it? There is a chance that either the tach is interfering with the signal or the routing or the wires, possibly too close to the ignition wires is sending a faulty signal.

The tach wire is unhooked, I put everything back to stock except the optispark. And it doing the same.. That what i thought at first the problem was.
