Odd Problem
fuel pump pressure surge change filter other than that vacuum leak
Fuel pump and filter changed already.
I doubt that it would be an intake leak, as Id expect popping, backfiring, missing, and oil burning. Maybe the vacuum valve on the brake booster?
Oddly enough, I tried swapping one or two ballast resistors and neither would work......unless I swapped on wire over to another post. The existing resistor is the only one that will work with the existing wire to post location. I find this odd, actually.
I doubt the odds are very good that two ecus could be bad.
This all started Sunday after some driving. The only thing that I did to the car was retard the timing just a hair before driving and it ran fine for a while, then developed an issue. I tried readvancing the timing, but it did nothing, and yes, the timing is right: 17* of initial as always. When adjusting timing, I only loosen the bolt just enough to twist the dist via the vacuum can, then retighten the bolt. I cant see how it could of jumping dist timing.
