I was attempting to set the idle RPM on my D-jet car. I've got a SunPro analog engine analyzer which uses an inductive pickup for the RPM setting.
Anyway, I attach the two leads on the analyzer to the negative (-) on the coil and the other to the negative (-) on the battery. If I attach the inductive pickup to either the #3/#4 spark plug wires, the idle is somewhat steady at +/- 50 RPMs. If I hook up the pickup to either the #1/#2 spark plug wires, I get the same +/- 50 RPM variances. But then I also get a pretty steady, say once every 3-5 secs., spike on the meter. It'll jump about 1000 RPMs. Any ideas? Ignition miss? Why does it only happen on the #1/#2 side? I am running new plugs, plug wires, coil, Pertronix, rebuilt dizzy, FI harness, etc... |

I guess to say it is a spark jump from one wire to aother possibly. After it gets dark tonight, start the engine and after it warms up look at it running with a little light possible. It might show a blue glow where wires are leaking. It could also be some sort of feedback into the inductive pickup and the Pertronix unit causing the spikes. Good luck

Good idea. I'll give that a try.
