Need help with truck/weird problem
I have a 96 F250 supercab 7.3L turbo diesel that has started to do some weird stuff. Yesterday when I left work I noticed that anytime I go 3/4 throttle or to the floor with the pedal the truck loses all power. Its like someone just turned the truck off. It stays running and doesnt actually shut off when it does this. The Wait To Start Engine light flashes and the RPM's drop to 1500 everytime it does this. Until you take your foot off the gas pedal it has no power. It's like its just idleing. Once you come off the pedal its back to normal. If you are in Neutral or park you can free rev it with no problems at all. If you take off and go to the floor it is fine until it shifts to 2nd and then it will do it as well. So I Ohmed out the TPS on the gas pedal and it appears to be alright. It wouldn't allow me to ohm it with the truck running though. The truck idles fine and runs fine throught the rest of the throttle travel. Just anywhere from right after 3/4 or to the floor it does it. I pulled my programmer off and put it back to stock and it still does this. The truck has 161,000 miles on it. The only thing I did yesterday out of the ordinary was I brake torqued it once goofing off out front of work. I stood on the gas for maybe 3 seconds and let off the brake and it layed a little patch of rubber for maybe 2 feet thats it. The other thing it decided to do on me this morning on my way to work was. Upon taking off from a stop sign I noticed the engine sounded loud and deep like I lost my muffler or something and I had thick *** gray and black smoke just pouring out the exhaust. I stopped and took off again and the engine went back to normal sounding and no more smoke. It drove fine the rest of my 40 mile trip to work other than you cant go to the floor with the throttle or you lose all power. Any help would be greatly appreciated as I am lost when it comes to diesels and turbos. This is my first diesel I have owned.
