hesitation/cutting out under acceleration??
Hey guys..I have a 91 f150 300 6....truck has been hesitating and cutting and almost shutting off out when taking off from a stop and then will take off and will run fine the rest of the time... its getting pretty bad as its doiing it everytime i go from a stop?
would a bad fuel pump do this?
or is it something else?
thanks

It's the Throttle Position Sensor, it tells your computer how much gas the truck needs based on how much throttle you give.
Also I'm guessing it's an EFI F150 right? Or is it carbed?
If it's carbed, then it could mean the carb needs to be rebuilt, or a faulty fuel pump.
There is a slight chance it could be because you have low fuel pressure, so I would check that before looking into the TPS.
Umm, as far as fixing it, I don't think you can, you just have to replace it.
Check out this link, it's about the symptoms we have, it's from FTE members.

i'd agree and assume it's the TPS. i just had the same problem that flared up a few weeks back and got worse until unbearable. at first it was my temp coolant sensor causing the engine to think it was running hot, but it wasn't. after doing that 5 min fix, the CEL was still on and the problem persisted. long story short, my buddy came by and read the computer, went and got the TPS, and replaced it. since then, i haven't felt the bog down that was there before. when you do replace it, take your time and remove the throttle body (and replace its gasket while you're at it) to make the install easier.
