What should TPS be on Ford 460efi at idle?
In those cars, having the TPS set to .80-.95 at idle was relatively important. If it was set higher than 1.0V or so, the ECU would think you weren’t at idle. If it was set much lower than .8 at idle, there would be hesitation upon light acceleration.
What kind of motor does a 95 Ford F350 have?
SOLVED: I have a 95 Ford F350 with the 460 motor. It – Fixya I have a 95 Ford F350 with the 460 motor. It started running fine when cold but after it warms up it starts to run rough, lose power, and runs REAL rich. I’m only getting a little more than 2mpg.
How can I Fix my Ford F350 engine?
The Mechanics are going to need some gas left over in it to work on the engine. Also turn on ignition and energize the fuel pressure, check for leaking fuel lines. Put on fuelcap locks if fuel drops when parked. For this much of an extreme problem, I would like to know what you find wrong with it.
Why is my Ford F350 forcing too much gas?
Change your thermostat. The onboard computer does not monitor operating temperature. Fuel pressure regulator. Have pressure checked.It could be forcing too much gas in each time an injector opens. If you can not do this yourself, tow it in. At 2 mpg it may be cheaper to tow it than to drive any distance for repair.

What causes an uneven idle on an F-150?
A uneven idle on a F-150 can be a symptom of a variety of engine issues such as vacuum leaks, failed or dirty sensors or worn engine components. If the engine is older or has higher miles on it, the typical culprits will be dirty sensors and carbon deposits on engine head components.
How to troubleshoot an idle that is going up and down?
Finding the ultimate cause of an uneven idle can be a trial and error process, but a cost-effective way to cure your F-150’s idle problems is to start by cleaning specific components to see if this restores a smooth and even idle prior to replacing components.
Can a factory 460 engine be swapped with an EFI engine?
You can swap in a complete factory EFI 460 engine from a 1988-1997. If you already have a 460 that is still good you can take the heads and intake from the 88-97 and put them on any 460 engine. A 460 will even bolt up to the same bellhousing that a 351M or 400 will.
Can you put a 460 engine on a 351M?

What happens if you have a bad idle control valve?
Since the idle air control valve is supposed to manage the idle speed of the engine, a bad valve will certainly throw that out of whack. It will cause the idle speed to randomly fluctuate to different speeds rather than stay at one constant speed. The idle speed may be too high at one moment and then too low at other moments.
What kind of engine is a 460 engine?
The 460 engine I’m using to upgrade my 72 came out of a 90 model F-250. It ran but had numerous wiring issues with the fuel injection and other systems. Even though I was swapping the engine to an older truck i wanted to keep the modern convenience of fuel injection during the engine upgrade.
