On my Lincoln LS that is always bad cop ignition coils

On yours i don't know the system or have diagnostic manuals
or wiring diagrams

I can tell you the APP (gas pedals) don't fail & the TPS Sensor
would have to be completey gone to loose both sides

On mine the coils spike the pcm & then come back on tps
& thus loosing that signal & you go into ETC Failsafe

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.

SOURCE: Jeep Cherokee won't start, turns off, etc.

Did you have the same cranking with no start problem with original engine or did the problem begin when you changed it? I would check codes if you have not already, and would also clean business end of idle air valve (next to tps) DO NOT turn the end plunger while cleaning or it may not seat properly. Do not loose the rubber "o" ring while working either!

SOURCE: Won't do anything when trying to start. Jump start and fires up on the spot, but dies when gas pedal not depressed.

Check the ignition coil packs. It sounds like a spark problem.

Replaced Throttle body throttle position sensors

There is another sensor mounted to the gas pedal. It has to communicate with the throttle body assembly. If the correlation is not correct between the two, the problem will persist. The throttle body assembly is usually the most common of the two, however the accelerator position sensor still gives problems.

Pops, while pushing the gas pedal, and back fires and smells like gas and shakes while pressing the gaspedal, on 91 jeep cherokee l 4.0
spark timing way off. or burned valves.
i dont think a 4L can change cam timing. (gears)
that is gross misfire,
so bad it backfires to the throttle body and air cleaner
in all cases is bad spark timing, or worse burned valves.
bad rotor & cap,?
doing a tune up get rid of that carbon tracked bad cap.
and timing magically works.

What does a throttle positioning censor for an 05 ford focus look like

I suggest you google 05 ford focus throttle positioning sensor. This sensor keeps you air intake throttle at the proper position when the engine is cold and changes position when the engine has warmed up. to locate the sensor, remove the hose that comes from the air filter housing to the engine. the hose you removed was connected to the air throttle. you can manipulate the position of this throttle by having someone push the gas pedal down slowly while you watch the throttle move. notice that the gas pedal cable is connected to the mechanism that opens and closes the air throttloe. also notice that beside this mechanism, you have an electric throttle positioning sensor. Pay close attention to the existing throttle positioning sensor before you remove it if you are planning on replacing this sensor. because if you do not install the new sensor in the same degree that the old one was in, you will throw the calibration off. word of advice. buy some throttle cleaner from your local auto parts. turn the car on with the air filter to throttle body hose off and have someone push the gas pedal down slightly to keep the engine from turning off. spray the throttle body cleaner til all the black crud comes off the inside of the throttle body. this dirty crud is what was making your throttle stick and not working properly.

OUr jeep starts but dies unless we push the gas pedal. Then once we let go of the pedal it dies unless we can get it into drive.

Sounds like the idle air control is stuck. This is a stepper motor that controls the amount of air the engine gets at idle. Usually this can be cleaned by carb and choke cleaner. There are 2 torx screws that hold this to the throttle body. It has 4 wires on it.

What function does the trottle have on my jeep grand cherokee laredo 2006? They tell me to replace it, so what is wrong with it? Thanks

There is no part that you could go to a parts store and buy that is called a throttle. The closest thing to that would be the throttle body that takes the place of a carburetor on fuel injected engines.
A carburetors job was to mix the fuel and air and permit the proper amount into the engine. The throttle body is pretty much just an air valve that opens and closes as you push down on the gas pedal.
It has a sensor attached to it that tells the computer what position the gas pedal is, and a computer operated valve that regulates air flow when you don't have your foot on the gas.
(both devices are replaceable) The body itself rarely fails as there isn't much there to wear out. (at worst it may need to be cleaned)
You also have a throttle cable. That is a cable just like the one that operates the hand brakes on a bike. It moves the valve on the throttle body as you push down on the gas pedal. The cable is replaceable as well. Cables can fray or break.
Now...What's wrong with it??? No one can tell you that or even guess because we can't see it and you haven't given any info about the actual problem....Even so, a solution would be an educated guess.
Bottom line is that if a shop actually told you that you need a new throttle, either they are clueless or you have mis-understood what they told you.

What is the throttle position sensor? my 2003 jeep delays starting unless i pump gas pedel. delay start is around 5 sec of grinding starter, with gas smell. fuel filter and pump are ok.

Believe it or not pumping the fuel pedal is no help. This is a fuel injection system not the old carburetor type. the throttle position sensor is a sensor to tell the computer were the fuel pedal is at it is sensing how much you are pushing it to send fuel to the throttle body.

does sound like you have a leak down problem after sitting a while you may still have a fuel pump concern

Sticky gas pedal

it is a dirty throttle plate. $280 is an absolute ripoff for a cleaning, it is about 10-15 minutes of work. They are probably quoting replacing the throttle body which about a $150 part.

Got to Autozone and get "CRC Throttle Body Cleaner". Remove aire inlet hose at throttle body with a screwdriver. Spray a *small* bit onto throttle plate, use clean rag or qtips to remove gum/varnish. Spray pivots and also clean around perimeter of the plate. Take it to an independent mechanic if you are unsure of the procedure.
