My car wont stay running when Im not on the accelartor when I get to low rpms it just cust off even if coasting to a stop at a light or turning a corner PLEASE HELP!!

Get another estimate way to high. Mike

Its time for another car Jerry.
The oil pressure light was telling you the engine was running on less than 10 psi of oil pressure, and the knock was a rod or main bearing.
Now that the engine has been run low on oil pressure for some time, one of the rod or main bearings is junk, and so is the engine.
By the time you replace the engine, even with a used one, you could take the same money and buy another car. Even if you took the engine apart and fixed the bad bearings, the rest of the engine parts are very weak from running without oil.

To start with, you have a throttle body instead of a carburetor.
On that throttle body is a component called an air control valve.
That valve is how the computer controls the idle speed. It should open and close the air flow into the intake manifold as needed.
Is the check engine light on when you are driving ? Have you checked the fuel pressure ?

I have a 98 Windstar and it would die when pulling up to a stop sign, slowing when coming to a stop or making a slow turn. According to Ford recall 98E03 EMISSIONS RECALL some vehicles may stall during deceleration when coming to a stop, during slow speed parking maneuvers and/or coasting thru slow sweeping turns. This may be caused by the Powertrain Contro lModule (PCM) calibration dropping the rpms too quickly during deceleration. This involves reprograming the PCM. The revised calibration will allow the engine rpms to drop slowly during low speed maneuvers to reduce the possibility of a stall. Call your local FORD dealership (have your VIN handy) and have them check to see if this recall has been performed on your vehicle.

Replace alternator and find where that light is grounded that makes it stay on.

Next time this happens without stopping or pushing gas shift tranny into N and then back into D and see what happens. The battery light came on because of low RPMs, no biggy.

spark pug gaps are critically important & can even stop a car from starting! start there!
then reset the timing!
computorised cars should be banned! lol

your idle speed too low.take it to a dealer.they have to reset idle.it should be 600-800 rpms.when you turn on air conditioner.the computer steps up idling to keep engine from stalling .your curb idle too low.

Most modern cars with fuel injection, have to maintain a certain range of fuel pressure. There is a schrader valve in the fuel line. At this point fuel pressure can be checked. Pressure is always present. This can be dangerous, even at low pressure. Hope this helps lbreen

timing belt?? check it before turning engine over again ,sounds like a couple of the teeth have sheered off
