I 'm having several issues (see below) with my pick-up and would be grateful for any suggestions.
1995 F150 Supercab SB, 2WD, 5.0L, AOD, 3.31 axle, 282K miles (no engine rebuild).
1. Starting
a) With ambient air temperature below 40 degrees, vehicle will crank, but not start unless the gas pedal is slightly depressed while starting. This is for the first start of the day only, all others are normal.
b) With ambient air temperatures over 90 degrees and with sitting out in the hot sun, vehicle will start and run normally only for the first start of the day, then with other attempts to start it will crank, run momentarily, sputter and die. Sometimes if the pedal is pushed to the floor while attempting to start, the vehicle will run but shakes and smells as if it is flooded.
2. Knocking (ping)
a) Once the vehicle has warmed up, it will knock briefly when accelerating from stop. Worse under load (A/C) and in much hotter or colder ambient air temperatures.
b) Intermittent knocking (light to moderate) when cruising at 60 - 65mph with little load.
3. Lack of power under load
a) A moderate headwind will slow the vehicle down and sudden gusts will cause the vehicle to momentarily buck or miss.
b) When climbing hills at highway speeds the transmission downshifts normally, but the engine appears to work very hard to get up long hills - I share the climbing lane with the eighteen-wheelers! This sort of load appears to cause increased oil consumption.
