Rough Idle and Smoke on Startup?

[jhavard]

This happens every morning before I go to work. I replaced the UVC harness, VC gaskets, pigtails, GPR, Glowplugs, and checked the fuel pressure at the shrader valve (50 to 60 psi). It runs real rough till it gets warm and blue/grey smokes pretty consistantly till the needle comes up off the bottom of the temp gauge. After its warm, it still seems to be running rich, hazing a bit at idle and the MPG's on this thing are retarded. It also seems to randomly fall on its faceand I cant replicate it at any given time. Anybody have any suggestions other than the glow plug system. I'm new to the PSD, so please take it easy. Thanks in advance guys.

the smoke at start up it normal but the rest i couldnt tell ya

[jhavard]

Yea I figured alittle was normal, but it seems kinda excessive. Lets say for example that the motor is wore slap out, why would it run and idle great after its warm. Also, my MPG's are basicly non existent to say the least, like 8mpg mixed driving, I dont tow and I dont dog it. Could I be having injector or HPOP problems?

Anybody else????? Does anybody offer oring kits for the injectors?

you most likely have a weak injector. i have had the same porblem twice now. i have the snap on modis scanner so it was easy to find because all you have to do is cut out a cylinder to find which one is not putting out. so if u can get a hold of a scanner with cylinder or injector cut out you can cut out each cylinder untill you find the one. hope this helps.

Ok thanks, I originally used a new soluis snap on scanner we have at work, but i didnt see a cut out test. Ill check around and see if i can find somebody that knows how to use it better than me, or find another scanner, thanks.

What year and how many miles? Sounds like injectors or O rings. Check compression?
