l400 stutter
Posted: Tue Jun 05, 2018 12:58 pm
Hey Guys and gals
Trying to suss out a new problem. I'm leaning towards injectors but wanted to get some other insight.
1997 L400 Gen 2
4m40
Cylinder head was replaced by mechanic
turbo rebuilt by myself with a kit - Was professionally balanced
EGR Plate blanked off with 1/8"steel
The van has developed a since doing the egr and turbo when going from load to idle. An example would be going from 60km/h to a stop light. It stutters a few times and then levels out. It's also started blowing black when accelerating and going up hill. It doesn't seem like tons to me but definitely noticeable in the drive side mirror. The stutter does seem to be getting slightly worse.
The injector pump main seal was changed about 40,000 km ago the one in the pump was still good, but it was trouble shooting for white smoke on startup that is still a thing.
Any ideas where to check or if i'm on the right track.
