It could be a coil depending on where the module was bought it could even be a defective module
I had a very similar problem with a 93 Buick regal. Finally got it fixed and found there was a problem with a cam sensor and it was telling the computer there was an error and the comp would shut the car down. This was a terrible problem for me to get fixed. Hope this is helpful, I feel your pain.
had the same problem with a Lincoln, was told the same things, change the fuel filter, and let me know, sounds stupid but it worked for me
When driving the IAC does not do anything because the car is not at an idle
No. A bad starter would cause the car not to start.
because it's a bad car
If normal movement meaning driving the car then YES
if you have a cracked distributor cap then water would get inside it and make your car stall.
because if you stop immediately then the car will stall.
Stalling while driving may be caused by a collapsing or kinked neoprene fuel line.
It depends on the gearing of the car. If you are in the highest gear and 40mph in that gear is under the idle rpm of that car than you will stall.
Year, Make, Model, engine size please. possibly an ignition or sensor (electronic part).
main fuel relay going bad. Eventually car will cut off while driving.
There are several things which could be causing the car to stall out while driving. The most common and least difficult problem is that the spark plugs may need to be changed.
A bad crank sensor will definitely cause the car to stall. Eventually the car will stop starting up again, or if it does, it will die down around ten minutes. A good thing to do if you're sure it's the crank sensor, replace it.
