So I've got this 94 F150 with a 302. It has recently been giving me some trouble. So it surges at idle and when stopped at a light, struggles to go up small hills and it has been giving me very poor MPG. Additionally, the check engine light will come on for a few seconds but will stay off for the rest of the drive. When the problems first started, my truck died when I was pulling into the driveway too. I just ordered spark plugs, wires, distributor cap/rotor and an 02 Sensor. Gonna be cleaning out the throttle body as well. Is there anything else I should look at? Thanks for the help.

 

May not be your problem, but I have similar problems and I've masked them by blocking my EGR. Actually, I just pulled the vacuum hose and plugged it, but my EGR seals well. My EGR tube is busted and I am sucking in fresh air instead of exhaust and it's been causing some stumbling due to the leaning out of the fuel mix.

 

Check fuel pressure. When my pumps started to fail it would throw the CEL because lean condition at O2 sensor.
