Visited the dealership to discuss my cold start problem - to re-state the
problem - when the engines cold, it starts instantly but will not rev - when
I try to rev I get smoke from the exhaust and it acts like it;s on 3
cylinders. It usually clears up with-in 100 yards - I put the pedal all the
way down and it gradually gains speed - while smoking - and then after the
100 yards it screams - running faster than at any other time.
The service technician asked about all the usual stuff that you guys
suggested I try - filters, leaks, etc - then he said he's seen a weak FI
leak fuel when sitting and leaving a pool of fuel in the cylinder. Then,
when the engine is started it is hard to burn before finally reaching a
temperature where it ignites and then it runs very fast. Sounds a lot like
mine.
So, I thought I'd get your collective opinion - if it sounds like a logical
possibility I'll have a diesel shop service the FI's in case that's the
problem.
I will do an oil analysis to see what the fuel content of the oil is - if an
injector is leaking there should be a high fuel content in the oil possibly
affecting the lubricating ability of the oil. Since I just changed the oil
I'll wait until I have 1000-1500 miles on the oil before I extract a sample.
The kit we sell has a bellows bottle and 4' of tubing to insert into the
dipstick - so the oil doesn;t have to be changed to get a sample.
What do ya'll think?? Sound like a reasonable course of action??
TIA -
