Hello members,
I have not posted in awhile, I am having problems with the 2.5, just installed new nozzels and it ran terrible until warm. I decided to put new glow plugs and a controller in also. I am still having the same problem.The engine starts fine, but after the after glow goes off it starts to miss and belch white smoke. I had the new nozzels re-tested and they said they were ok.
The one thing that I think is going on is the valve in the intake is not opening quik enough or some thing else is happening.
I can not find any info on the operation of some of the emmsions equip on this engine. Can anybody enlighten me on what happens on cold start days and what valves should be open or closed. Just a note, after warm up, this engine is smooth as silk and has plenty of power.
any help would be greatly appreciated as this car has not been on the roan for weeks.

Thanks
Peter
