My 94 Z28 Camaro

Hello everyone i have a 1994 Z28. I've had her for about 5 yrs. She now has 152k miles. But recently i have been experiencing problems with her shutting off while driving. At first she wouldn't start back up til hours later or next day. So i would have to get her towed home. I got a diagnosis from Savannah Tire they gave me codes 16, 22, 36, and 48. Since then i have changed and installed new fuel pump, new fuel filter, new ignition coil. So now when im driving she still cuts off but will start back up. I had the plugs, wires, and optispark distributor changed a few months back around last year summer. But i bought a cheap opti from a website online. I Really need help i love my car.

I would take the ignition control module ( ICM ) off, take it to a parts store and have it tested.
Have them test it more than once so it gets heated up.

^Agreed. This seems to be an ICM issue and is fairly common with the LT 4th gens.
