Default D15b7 problem

I have a 94 eg coupe. I have replaced main relay, spark plugs and wires, and fuel pump. When I crank my car its perfectly fine until it starts warming up. Then the car starts hesitating then just cuts off. After it cuts off the fuel pump and fuel injectors keep cutting off and on( like 4 or 5 times) then stops for a second or two then does it again and so on. Does anyone have any idea why??? Thanks for any help/advice

If the ECU gets intermittent signal from the distributor it will effect injector pulse.

The first thing I would do is clean your grounds. In particular, ground G101.

It is the ground on your thermostat housing on the engine.

After that I would begin investigating the distributor by doing the ICM and coil tests.

Stupid question but where is G101? In the ECU?
