Have a problem with a ford f-150?

Question

Have a ford f-150 and when i stop it shuts down. Took it to the shop and had it checked in the computer and told me, the truck doesnt have enough spark so the spark plugs, spark cables were changed. What can it be? Thinking of changing the oxygen sensor

Answer 1

Hey thanks everyone for dissing this guy's truck, way to be helpful. But anyway you said that it doesnt have enough spark and the plugs and wires were changed, but how are the distributor cap, rotor, and even the coil doing? Those would be my next guess, also check for condensation inside your distributor cap, that can be solved by spraying starting fluid inside that cap and let it sit for about 10 minutes or so.

Answer 2

Don't just start replacing items. If the O2 sensor is bad, it will limit the amount of fuel, not the spark. If there truly isn't enough spark, the problem will lie with what causes the spark, i.e. the ignition coil, or coil packs. (I am not familiar with what is on your vehicle). I would check the throttle position sensor, since when you stop, you should be at idle, and if your TPS isn't adjusted properly, it will halp cause a stall. Take it to the dealer rather than a "shop", and they might also have a better idea than a general mechanic. Good luck.

Check for heat at the heater hoses, if they are both hot, the problem is probably the "Blend Door Actuator", it is an electric pancake motor that moves the "Blend Door" from hot to cold, also sometimes the shaft that the actuator operates will snap, in that case the dash comes apart for repair, Not a small job. You might remove the glove box and check the motor on top of the HVAC case to see if it is moving when you move the temp control from hot to cold and back. If not the actuator is dead. Common on Fords.

Answer 4

O 2 sensor most likely have you checked the alternator for a short?

Answer 5

You didn't say what year it is but there must be a way to idle it uo a little higher. Leave it in "P" and get it up to around 800 RPM.

Answer 6

Its your IAC (Idle air control) valve, It should be located near your throttle body.. Check it to see if its dirty. If it is, replace the whole thing (60 bucks). When these go bad, cars will die at idle.

Answer 7

the problem is very simple... the 150 should be a 250.


problem solved.

Answer 8

the biggest problem of all is that you bought a ford, doesn't surprise me you have all sorts of problems with it

Answer 9

it is probably your alternator or your battery

or maybe a low idle
