What have you done to your DeLorean today?

[DMC5180]

Well today I checked the fuel pump current at 6.3 amps. engine off so that looks fine. Since I was in the washer bottle area I though maybe a connector for the fuel pump wire got moved.

I then put a spare ignition ECU replacing the bolted one and test drove at no change (still skipping under load).

I then pulled the plugs and gaped them at less than 0.030" but more than 0.025". I had them gaped at almost 0.040". That really helped with almost no skip under load but I still think really heavy load it may still have an occasional skip. So it looks like I need to replace the distributor cap and rotor next.

Any other ideas before I order a new cap and rotor?

This definitely, appears to be symptomatic of worn spark plugs. Are you running the stock Coil? How was the weather at the time. Very high humidity/wet conditions will cause arc jumping if the wires or cap/rotor are breaking down with age. Fresh plugs/wires/cap & rotor should clear things up so long as the fuel mixture isn’t running lean.
