Hello!

When putting voltmeter + on the other pin on the primary or secondary clip and voltmeter - on negative battery cable i get a slow and steady discharge from 5-6v down to 0, which makes sense since the voltage is discharging/getting used This makes no sense, you should have constant 12.4 on each terminal key on, the ECU briefly grounds the injectors to fire them, so brief you’d never see it without an oscilloscope. Recheck to confirm. Also the injector resistors don’t alter voltage, they limit current.

I like it Randy!

Injectors don’t care which way they are wired, it is best practice to do it the same for troubleshooting. It sounds to me like you’ve got debris in the pintle of one or both, happened to me years ago with my 87. I had to remove both injectors and flush them backwards to finally fix it after several failed test drives.

My 87 has run a wideband O2 mounted in the factory spot for 30K plus miles without issue, still working fine. If you’re still running the factory ECU you can run the narrow band output from the wideband ( most have them) to the ECU.

Hey Nick, good to hear from you!

It can be the ABS system as well, that module is in the rear hatch.

Still have 3 in AZ.

Both sets sold.

I’ve got 3 but they’re sitting at my winter house in AZ.

Sold!

One set sold, one remaining.

Revolution (I think?) big brake kit, 300 mm diameter, I had them installed on my 87 MPI with factory front 7" wheels, ended up putting the stock setup back on with the intent to put these on my 85.5 which I just sold. Rotors are supposedly BMW units, they are very thick and heavy, included along with the brackets, wheel spacers, ss brake lines, all the nuts and bolts and clips and Wilwood four pot calipers. Very lightly used, street only. $500 shipped to the lower 48.

Sold!

I've got two sets of D2's NIB sitting in my garage, no longer needed. $1000 each shipped to the lower 48.
