Accelerater problem while driving highway speeds the gas pedal will suddenly stop working. After pulling over and killing engine for a while it works again

run fault codes and look for a faulty TCM unit

With the oil light coming on and the brake pedal being hard to press I would say that the engine stopped hence no vacuum -no power assist from the booster.- hard brake pedal. The lock uo feeling may come from the engine seizing up while you were still in gear

It sounds like a vacuum hose popped off somewhere.

The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

I HAD SIMILAR PROBLEM MY 2005 PT SUDDENLY JUST SEEMED TO CHOKE DOWN AND PUSHING ON GAS PEDAL MADE IT WORSE SO I LET UP ON PEDAL AND THEN SLOWLYMPH ACCELERATER BUT I WOULD ONLY GO ABOUT 50 MPH AND THE ENGINE LIGHT CAME ON I CHECKED OIL IT WAS FINE I THEN PUT A CAN OF SEA FOAM IN GAS TANK AND DROVE SLOWLY A WAYS THEN SPEEDED UP IT RAN FINE SEEMED TO BE DIRTY INJECTORS OR FUEL PUMP. I WNT ON HOME THE ENGINE LIGHT STAYED ON THE NEXT MORNING THE ENGINE LIGHT WAS OFF AND IT HAS RUN FINE EVER SINCE

Sounds like the transmission is slipping, have it checked.

Sounds like throttle position sensor is not working properly.



Good luck

If battery has power, check if other things work or not. If you mean "won't turn over" does starter relay Click? If there is only silence its a different problem. Check the oil level, some cars will kill the ignition at any speed for low oil level. The timing belt would not stop the engine from cranking. Starter relays usually aren't fused. Check battery cables.

Whne I worked at Ford , they had problems with the accelerator pedat electronic switch. The pedal is not connected to the engine with a cable, but with an electrical connection. You would have to have a scanner put on your vehicles computer and check for any trouble codes. Also give the Ford dealer your VIN # and they can check for recalls for that problem.

check your oil dip stick if the oil is milky its your head gasket
defenetly sounds like that to me
