I have the car at home. I drove it all of the way and only stalled it once, just checking to see if it would idle at all. Obviously not.
I was able to keep the engine running with judicious throttle application and slipping into neutral while rolling to a halt at traffic lights (not many I know the back roads here well).
While driving at 50 MPH, the engine pulls well (I am used to a non-turbo 300D remember) and tranny kicks down to 3rd on full throttle.
Below 40 MPH, there is an intermittent miss and backfire thru the aircleaner at neutral throttle.
From a standing start, I can have the engine at 1500 RPM (irregular firing) and slip it into D. The engine RPMs drop, but with slightly more throttle application it pulls away well without any obvious miss. I am not talking WOT acceleration.

I tried WOT acceleration as well and the car moved out well, although with that engine I thought I would have some loss of traction.
Tranny shifted well, up and down the gears, although I didn't check 3-2-1 while stopping, as I was in neutral nursing the throttle.

Possibilities:
1. Burnt valve (s) or other compression issues
2. Fuel injection issues - pump, injectors, etc
3. Spark issues - dizzy cap replaced by mobile mechanic for PO with no changes to symptoms. Do these engines have electronic ignition?
4. Anything else??

I will pull the plugs to determine which cylinder is not firing well, and do compression test on each pot while plugs are out.

Can anyone help me with diagnostic tips for the fuel injection?

Thanks,
Tony
