02 LB7 really PI$$!NG me off! No power!
I have an 02 lb7 that I've been trying to fix a lost power issue for a couple weeks and nothing! Well today after messing with it I got mad and run the hell out of it on the way to work and bam it started running PERFECT for about 10 minutes then I stopped at the store and when I came back out and left it had no power once again!
What I've do so far: new fuel filter, cleaned MAF sensor, run the recommended amount of power service in this last tank of fuel and nothing helped. It has newer injectors with good balance rates and a 6 month old cp3. No grey smoke, fuel in oil, or anything out of the ordinary. It has a predator programmer, factory straight pipe, and cold air intake. It's a cheap eBay intake that the original owner put on with a K&N filter i put on it 2 months ago and I've had problems with the filter falling off about 3 times! Do any of y'all have any suggestions? Maybe bad fuel? Dirt or something in the turbo from that cheap pos intake and the filter falling off? It has no cel or codes except p0380 for glow plugs so i don't know which direction to look. I also don't see any fuel or boost leaks and don't understand why when I ran the hell out of it the power came back for a little while.
