I have a 95 F150, 5.0, Auto Trans, 2 wheel drive and I'm having some problems I cant seem to figure out. The truck doesnt seem to have any power on acceleration. I can floor the gas pedal and it goes nowhere. I can get it to 70mph but its takes forever. Feels like my passing gear isnt there but it does shift fine through every other gear. No knocks, tapping, grinding anywhere. I have replaced timing chain and gears because they were stretched, new plugs and wires, the timing is set correctly (done with spout removed), there are no leaks that I can find and all fluid levels are good. It has a MSD distributor and coil and I have went over firing order just to make sure that was right as well. Even before doing all this work the truck seemed to have a little more power one day and then none the next...its a hit or miss with this. Im so confused. Can anyone give me some idea whats going on please???

Oh yeah...check engine light came on before I replaced plugs but is now off. Never got a chance to check codes prior to that but no codes are showing up now.

 

Does that mean the CE light isn't on or that you got 111 when you connected the code reader?
Did the problem come on slowly or overnight?

 

bumped for buddy

 

From what you're stating, i can tell everything related to the spark and sensors is fine, the next thing you should check is the fuel supply, the filter, the pump, and take a look at the air filter. If you have a Cat. converter, it could be plugged also, see if the exhaust has a rotten egg smell (that would point to a cat. failure). Welcome to FTE btw!

 

The light went off so I didn't bother checking the reader. I will do that today tho and see if anything shows up. I put a new fuel and air filter in it so i dont think the filters are causing anything. I havent checked the CAT but I dont smell any rotten odor so I wasnt sure if that could be the problem either. This all pretty much happened overnight. It was running fine but I could tell timing was a little off so I timed it and it wouldnt really hold the timing. thats when i checked the timing chain and saw that it was stretched really bad so I replaced that and reset timing correctly...as well as doing plugs and wires. But I still dont have and pick up when I floor the gas. Should I disconnect the CAT at the donut and try running it to see if that makes a difference or at least to rule at CAT? Could it be the torque converter?
