Hello all.
Looking to see if anyone can help me out with a little problem ive been having. i have a 2011 navigator that has been stalling at start up lately. when i go out to start it in the morning, it turns over, sometimes for a few seconds, then kinda starts, and stumbles a lot. when it does finally start, it blows out what looks like black smoke, and smells really rich. once this clears up, it runs fairly well. i say fairly well because it also hesitates as you accelerate. ive had 5.4's and v10's before, and it almost seems like a COP, but if i tramp on it hard, it goes away. only under light throttle does it do it. or in a heavy headwind.
i changed the plugs, and looked at the COP boots, and they LOOKED ok. but when it gets warmer, i intend to buy the accel coil packs. it seems like it is a leaky injector, or the computer is reading the wrong info to start? i should also mention that it seems REALLY hard on fuel compared to my previous 08 expy. with or without the programmer.
ive searched high and low for the same problem from someone else, and there was only one thread where the guy had the same problem, but was never answered. so i dont know. also was wondering if it could be something to do with the egr sticking? i do have it 5star tuned, but this problem was showing up before,along with a P130 and P150 code, for O2 sensors. i have just recently replaced all 4, and these codes no longer come up. but my problem is still there.
hope someone can help. its draining my wallet on fuel running around for hockey!!!
thanks all
