Hey guys, I have a 95 F150 with the Inline 6 4.9 in it. I got some gas from BP the other day (10 bucks worth, so not too much), and the truck developed a studder, like how it falls on its face when its running out of gas, acting like the motor is shutting on and off starving for fuel. Well I put 10 bucks worth of speedway gas in yesterday, and it still does the same thing, and it idles very rough sometimes. It doesnt matter if im idling or going 60-65, it always acts like it is running out of fuel like the motor is starved, however when I get out of the truck, it reaks like gas. I have dual tanks, and I have pretty much 0 knowledge, but I was wondering if maybe the front tank fuel pump would be going bad, and I could simply start putting fuel in the rear tank and running it out of there (just habit to run it out of the front tank. I also noticed last night if I floored it, it had no get up and go, and ive personally never heard spark knock, but my friend that was with me said it sounded like it. Ive heard it could be cap and rotor, maybe plug wires, maybe plugs, but I have no definant answer. Its my daily driver, and only driver, so it needs to be running good asap, as im afraid to run it how it is.

Thanks Guys,
Erik

PS, no check engine light is on if that makes a difference.

 

Change fuel filter and dry gas it. Sounds like you have some water from the BP station most likely. I have not and will not buy BP gas.

 

hey man thanks for the quick reply, is that the only thing you can think of? Im gonna try and check everything out tomorrow, and Ill have it in a shop, so id like to check over everything else while im there. What else could possibly be an issue?

 

Could be a bad pump but I doubt it. Check your tps sensor also but that usually throws a light code. If it did not start until after the gas from BP I would suspect that is the culprit.

 

changed the fuel filter and that wasnt the problem, ended up changing the cap and rotor, runs like a champ now
