I have a 2001 24 valve and it has no power and smokes  white like crazy when its cold. It will do this even after sitting for only 2-3 hours if i let it idle for 25 minutes or more it will be fine still some smoke some not alot more in 1st 2nd and a blueish tint but lots power. Not getting a code for vp44. I have the air intake sensor unplugged all the time because when its plugged in then it has no power almost all the time. Once trucks been running for 25-30 minutes it works fine but it will lose power  right at 1450-1500 rpm in 3rd 4th 5th if u hold it there for a while, usually happens if i get stuck behind slow traffic and im at that rpm.If i drop a gear to bring the revs up or go through the rpm without stopping at that rpm its fine. Trucks only got 270,000km yes im from canada lol. Any help would be greatly appreciated or if someone has had a simillar issue. Thanks in advance. 

Error codes? P0216 code will not trip the check engine light

 

Fuel pressure? Optimal 14 to 20 PSI.

 

270km equals 167k miles. It possible you injectors are worn out. My factory injectors ran 150k miles and pop pressure was down way too low.

 

 

last time i checked im getting p1693, p1492 and p0122. Ill check them again tommorow and  get back to you. As for fuel pressure i had installed a new in tank pump because truck was converted before i bought it. And i have a fuel pressure guage getting 25 at idle and 15-20 at wot.

0122 apps voltage too low

Get a Timbo apps and be done with it. 

Look in store

1492 battery temperature sensor, should only be in charge of telling alternator how much to charge. 

 

By unplugging air intake temperature sensor and making it run better, you might be messing with ECM timing tables. But I'm still not hundred percent sure on this one. You should have a code for it also. 

I would get a live data tool and watch the ECT and IAT numbers. Both IAT and ECT should match on a cold morning start. Then IAT should run about +40F to the outside air during the summer. Being it winter time it might be closer to +60F over outside. Sorry, I don't know the offset amount for C (Metric).

So i checked the codes again with the key im getting p0500, p1492 and p1693. With my scanner im getting p0113 air intake unplugged, p0216 and p0341 cam sensor i have a new one but never installee yet. I have a live data scanner but havent got to check that yet.

you have a tired VP44 along with other issues.
