1991 Ford F150 6 cyl Four Wheel Drive Manual unknow miles
My truck is idling rough and hesatating on acceleration. Problem began suddenly not getting worse over time just started like somone flipped a switch. I have replaced the TPS, the EGR position sensor, new set of plugs, wires and cap and rotor. Also I replaced the MAP sensor. I made a gasket to plug the egr to verify it wasnt leaking by. I have checked for vaccume leaks and leaks in the intake manifold. I bought an obd code reader and the only code was for a non responsive purge canister selinoid I checked it and it was indeed stuck open causing a vaccume leak. Fixed that problem and that did help the idle quite a bit. So there is no check engine light, and I suppose worth mentioning its a real pain to start. It is way worse when its cold but when its hot it still dosnt start easily. Thats about all the info I have so let me know what you think. And thank you in advance.
have the same problem?
