2000 F150 4.6L Triton V8 Problems
I need some help people. I inherited a 2 wheel drive 2000 F150 with a 4.6L Triton V8 from my grandfather when he passed. The truck only has 136 000km on it, was ALWAYS parked on the grass for the 11 years that my grandfather owned it, and sat for a little over a year without driving at all while he was sick.
Now I'm getting into the troubles:
- I started driving the truck in the summer of 2011. When I first started driving the truck, I noticed that there is a very high pitched squeal that only occurs when the truck is either idling or when I'm slightly pressing the gas pedal (such as going through a drivethru), but it only happens periodically and usually doesn't happen more than 2 or 3 times per drive.
- About 5 months ago, I changed the front ball joints, rear axle seals, rear brakes, and put a new differential cover on because the original one was pretty well rusted all the way through.
- A couple of weeks ago, engine started slipping (in my opinion). It revs right down like its about to stall and stays revved right down. When I get on the gas, I can feel the gas pedal shaking and actually the whole truck feels like its shaking; This also happened a couple of times while I was driving. As I hit about 70-80km/h the engine revved right down, felt very low and power and than the shaking started again. Like the high pitched squeal, this doesn't happen all the time, only periodically.
I'm not great at diagnosing engine problems and I just bought a house so money is tight right now, anything anyone could say/do to help me out a bit would be really appreciated. This truck has a great amount of sentimental value to me, and if it can be fixed, I would rather fix it than buy something new.
