My 87 190 2.5 turbo diesel continues to be a bit rowdy on cold start. It smokes and shakes for a bit until it warms up. The glow plugs are new and most of the obvious culprits have been addressed. I'll eventuality sort it out.

Anyway, here is something I noticed...

Immediately after starting the car, I throw it into reverse and back it out of the garage... It would appear that the car runs a lot smoother and there is significantly less smoke when the car is in gear and the accelerator is slightly depressed.

If the car is NOT in gear and the accelerator is depressed slightly immediately after a colt start the engine will run rough and smoky.

It would seem that a slight load on the cold engine helps cut down on smoke and the engine runs significantly smoother.

Any ideas as to what is going on?
