Can I fix it myself or is there a recall on it? I'm disabled and just bought this car in Feb. With 242000 miles on it. Since then tranny, problem s ac problems oil pressure drops to zero once in awhile and almost over heats. Help are they all tied together?

The car squeaks over bumps, especially noticed at low speeds, maybe can't tell when going faster due to road noise. Suspension seems tight and no squeaks when I push on the car and I have lubricated everything I can think of.

I have already checked the antenna connections and they seem to be tight.

Would it be better to just have a certified mechanic do it?

The oil light will say low oil pressure but the truck starts right up and oil pressure is normal. Only happens once in awhile in the past 8 years.

I can drive over larger bumps and not hear a thing.

Change oil light comes on every time I turn the car on, but goes off about 30 secs, even after getting oil changed.
