Question about 1989 Ford F 150
1989 ford f150 w/ 5.0 liter 4x4 ..... check engine light and engine light on and when cold the truck will start and idle but when you try to move the truck it kicks and backfires under any throttle load. when warmed up the truck will shut die and not restart. i replaced fuel filter,plugs,wires,cap,rotor button, and air filter. timing is correct and when warm it retards 5-7 degrees. any ideas or help is welcomed
I would check the oil pressure of the engine. The reason is the timing chain tensioners are run with oil pressrue. I think your timing chain tensioners are leaking down when engine is getting to operating tempature . The oil is thinning down as warms up , as it should to lubercate . I would check compression and do a cylinder leak down test on all the cylinders. Then if the compression is good and the cylinder leak down is good. I would change all the timing components, ( chain, timing gears, timing chain tensioners )
Good Luck , I hope this helps.
