Like the title says, my 5.0 powered 94 auto f150 started sputtering randomly one day. It would come and go every now and then but eventually it got to where every time I'd go to drive it, it'd start sputtering ONCE IT GOT UP TO OPERATING TEMPS.

It's like the truck is starving for fuel and sputtering and the CEL comes on briefly and when it starts driving normal again, the light goes away.

I've already changed the fuel filter and cleaned the air filter. Does it on both fuel tanks as well.

Also when I go WOT it runs like a champ, and idles fine and revs fine in neutral or park. It'll take off EVERY TIME I mash the go pedal to the floor.


It started doing this last October, and I just parked her because I have an 03 Cobra I drive daily. Well drove daily. I lost all compression in cylinder 7 last week in her so I need to get my truck running right again while I have my cars motor tore apart.

Thanks in advance! Here's a pic of ole Betsy. 1994, automatic, pw, pl, ps, cold ac (that's never been charged-not once) keyless entry, k&n intake, no mufflers but still has cats, Ford Racing 3.73 gears in the rear (had 3.08's stock!). Bought it from my father in 2007 after joining the Navy and he's had it since it was practically new. It's now sitting at about 165,000 miles. Original paint, except for the hood.

Wow, nice looking truck. Start with pulling codes and go from there.

ademily87

Will there still be codes stored even if the CEL isn't on?

ademily87

And thanks!

Nice truck.

I'm not sure if you will have codes without the light being on constantly, but I would try it. Also, I would consider testing the tps if you haven't already.

Aktech

If there is any, yes.

Whenever the light pops on ( and even sometime when there is no light ) a code is stored in memory.

dr_bowtie

check codes as others instructed... check TPS signal with DMM and clean and check ALL Grounds!

I tried pulling codes. Couldn't get my reader to work and once I did I got distracted and lost count of flashes lol Gonna try again in a minute.

After this beer or 12.

So I plug in my actron obd1 reader and the "self test output" light comes in while its in "hold". I then go in my truck and turn the key to run, get out, shut the door, and turn the switch on the tester from hold to "test". The sto light turns off, my fuel pumps kick on, some relays click, and that's all that happens.

Bad tester? Guess I could try the jumper method just to verify.
