Havin trouble!
I have an 85 F-150,302fi i'm having trouble with the truck when it warms up, it seems like it's running out of gas,bucking like crazy it will idle fine and i can rev it as much as i want, but as soon as i go to give it gas it starts bucking!Here's what i have replaced,front fuel pump,frame fuel pump, fuel filter,coil,mag. pick up,engine ing. module, thottle postion sensor,getting ready to put the coolant senor in later,also when a friend of mine put a computer on it,it said low voltage to the TPS,what would cause this! Sorry about the long post!

You need to hang around your friend who must have the code reader. The computer monitors it's systems, and when it sees a problem, it gives an error code. If it is still giving an error code for the throttle position sensor, even after you replaced the sensor, you might have a wiring problem.

Well, if you click where it says "this link", you'll understand how to pull the codes and you won't have to keep buying unnecessary parts.

DTC - Diagnostic Trouble Code
PCM - Powertrain Control Module = EEC - Electronic Engine Control = OBD - On-Board Diagnostic
The "full code list" link on that page will show you the way to hook the jumper wire up.

When my truck was acting like this (flooding down like?) it was the heat sen. It took me about 3 times taking it back for a new one til i found one that was good. Just because you bought a new on dont mean it'll work. be sure to unhook your while doing it, So the computer will clear it's codes.

Thanks man i'm gonna give it a try! I never did unhook the battery,i'll do it though! Also when we had the distributor out,good thing i did take it out it was ready to lock up,the shaft was all rusted! I got it out of time and i need to set the timing,is there anything i need to unhook,it's not much out of time because it runs good(for as long as it runs)!Thanks again for the help, i've learned alot so far off of this board already!
