Misfire under load
Here it is ! I have a 1994 Ford F-150 5.8 with 4 spd auto . Only addition is a K&N air filter in the stock airbox !! The truck is showing no codes in the computer , so the computer isn't seeing the problem !! At idle will have an intermittent miss , as you lightly accellerate it will go away ,but if you're trying to pull a hill it starts to miss worse unless you really fire into it then it runs almost perfect, with just a very small amount of miss !!! I've replaced these items FPR ,MAP sensor ,TPS , plugs ,wires ,button ,and cap ,fuel pump ,fuel filter , whew 'bout to pull out my hair . Any help would be appreciated !... Thanks in advance ... cougar
