Help!!! When the ambient air temp is above 80, which is most of the time in texas, my 86 F150,302 FI, runs really bad, the engine cuts out and stalls when accelerating. To date i have had the puter replaced(2 times), all sensors checked(supposedly are all ok), the throtle position sensor changed, ignition module, fuel pump(2 times), timing adjusted more times than i can count, coil, plugs and wires, intake manafold gaskets and untold hrs of adjusting by supposedly qualified techs including 1 ford service manager. ANYBODY GOT ANY IDEAS?????
