White smoke and missing
 

OK, I have read many posts about similar problems and have not found what will fix this problem. It started 4 days ago with my truck starting to miss and run rough after a couple of hours of using it. It seemed to have lost 1 or 2 cylinders of power. Got it home and started reading the forum. Checked all 8 injectors, found only number 1 cylinder to be sticking when it is cold. After it warms up it works fine. Replaced the odd side injector wiring harness (because I broke the clip by accident). Put everything back together to check it and than, after warming it up, started getting white smoke at higher RPM's around 1800 or so. The white smoke wasn't present when this problem started. Did I fix one problem and gain another or is this still part of the same problem? Still seems to have the miss and loss of power problem I started with. Could this be a fuel pressure problem? The pump has never been replaced although I changed my fuel separator recently.

white smoke equals

bad or warn injectors, bad injection timing, or cylinder compression is low.you need to do a compression test to rule out anything inside the engine.

Im guessing you are talking about the 2002 7.3l

I have 2 sticking injectors number 1 and 4... but they work after it is warmed up. Had a buddy come by and check it out because I need this truck running, you know money and all! He performed a buzz test and a few other tests... told me to change the oil than we will retest if that doesn't fix it. Doing that now. If that fixes it... :argh: :ouch:

UPDATE........
Still having trouble with the cold start thing but I think I have that beat as well. :jump:

All other symptoms seem to have gone away. Who would've thought that all of the work on the truck over the last 5 days could have been avoided by a simple oil change. I feel really stupid.............. oh well I guess it's all good and I learned something!:s:

OK..... Problem reappeared again! Loss of power, rough idle and feels like it's missing. Is it possible to have intermittent injectors? Possible IPR or ICP sensor? Anyone have any idea?
