Hi, i just bought my bronco( :D ) privatley. It's been sitting for about 2 months, just because the owner bought a more economic vehicle. And with 150,000 miles on it, im a little worried about the engine. As i said, it was sitting for about 2 months, however, on the test drive, it fired immediatley, and i let it warm up for about 4 minutes. Now, when i put it in gear, when i pushed passed about half way on the accelerator, i could a pinging noise( :? ), and i think its the lifters. It happened every gear, in that throttle range. Now im not that great with engines, but im not sure if its the throttle body, a broken engine mount and the engine is just shaking, if its the lifters, or it was still just too damn cold. I was planning on getting an engine rebuild kit anyway and doing it myself, but i just need to know if its something else( :evil: ). My friend said it was probably just cold after sitting... But, Any feedback would be GREATLY appreciated! Thanks! (2.9L V6 by the way, stock)

If the oil hasn't been changed recently change it and put a bottle of Marvel Myster in with the motor oil see what happens???

Sorry, i should have included that in the body, its a 1990 bronco II, so i dont think its a manual fuel pump.

And i forgot he mentioned that... It is due for an oil change and a full fluid flush. Could it really be as simple as an oil change? BTW, what will the Marvel Myster do?

P.S. - Thanks for the fast responses!

Yes it could be! I'm a firm believer to look at the obvious rather than jump to the expensive stuff right away. You should also try running a bottle of isopropyl dry gas to remove any foreign contents that may have accumulated in the old gas, with at least the recommened gallon amount in the tank. I owned a 90 ranger w/2.9 and it only liked super unleaded fuel.
If that doesn't do it I would likely recommend having the computer checked to be sure your timing is advancing with load
