A stumble or misfire,especially when the vehicle stall when coming on to a stop sign are 2 things for concern, A Cam position sensor which are prone to set a rolling engine surge and a stumble.

I found this picture online for you showing the location of the sending unit.

it's either low (in spite of your readings) or your a/c clutch is not working correctly or you have too big an air gap in the clutch.
First, just disconnect the 2 pin connector from the a/c pressure cycling swithc and jumper the 2 pins with a wire to force the clutch to stay engaged. See if it blows cold then, and stays engaged. You can run this way for about 15 minutes before you have to pull the plug.
report reulsts.

Generally if your fuel pump goes out than it is out. If you are experiencing errratic behavior with the motor and you believe it is something to do with the gas, try changin the fuel filter first.

Your code designates an Intake Air Control circuit malfunction. Without proper scanning tools, you will probably have to take it to a qualified mechanic. Sorry I can't help you more, but without the car, that's all the info I can give you.

The brake switch is an input for the shifting out of park... the wire might be chaved and making contact with ground. Inspect all the wiring around the moving parts, it should be visible... ggood luck. If you need further help, I’m available over the phone at https://www.6ya.com/expert/robert_573a00ba7e399076

The seat bottom is held in with 2 release buttons located left and right of the center of the seat. (see photo) push with a screw driver and lift, then pull the seat bottom forward and remove.



The rear seat back is help in place by 2 self tapping bolts on the lower left and right of the seat back near the floor, if I remember correctly you'll need a 10mm socket. Remove the 2 bolt and lift up to remove the seat back. When re installing the seat back do not over tighten the bolts they have a tendency to strip.

Hello and welcome to FixYa!

You may just have system failure. As a first course of action, I strongly suggest that you remove the positive battery connector and let it sit for at least 5mins. before reconnecting it. This will reset the system and can get your vehicle back to it's normal operation.

This thing really happens and reconnecting the positive battery connector serves like a jumpstart to the vehicle's PCM (powertrain control module).

Hope this helps and thank you for using FixYa! Have a good one!

Check the AC fuse, It's located in the power distribution box under the hood, just forward of the strut tower on the drivers side.
It's a 20 Amp fuse in position 24.

The fuse block diagram is in the owners manual, if you don't have a owners manual, you can get it at this free Ford website to view or download.
It's on page 163.

try to do this with 1/4 of a tank so the weight is not as heavy,disconnect the fuel lines and vacum lines,electrical connections when you have access to them,undo the filler neck to the tank and undo the gas tank straps with a jack under the tank to lower it slowly to remove.

The fuel safety switch is located in the trunk on the drivers side just forward of the tail light.
You'll have to remove the drivers side trunk carpet liner to gain full access to it.

try spraying starting fuid into the throttle body and see if it runs then for a few seconds. If yes, check fuel pressure. It should be 34 psi with engine running, 40 psi key on engine off. More liley th pump in the fuel tank.

This problem could be fixed by a new thermostat, however if this does not fix it then you may need a new head gasket or some deeper motor work ( which is why they want to do a new engine) most shops these days do not want to get onto motor work, the reason being is, it is expensive and timely, and often makes the shop "resposible" for every little problem that happens to the engine afterwards which isn't worth the trouble.
