Engine Performance problem
1995 Ford F150 V8 Two Wheel Drive Automatic 140000 miles
----------------------------------------------------------------
I have a 1995 f 150 5.0l engine ,idles and runs good has good acceleration from a stop, but at 40-50mph it has poor acceleration, will slowly build up speed but seems to be not much power. Changed fuel filter, checked compression 95-100 psi all cylinders,new plugs,wires ,dist. cap &rotor. check engine light code indicated throttle position sensor. or possibly egr position sensor? what do you suggest?
