The refers to a 78 280Z with a stock motor. The engine cuts out at about 2500 RPM, like there is either no spark or no fuel, it drops to about 2000 RPM and then runs again till it reaches 2500 RPM. Anyone know what the problem might be?

Thanks'

I have figured it out somewhat...first it was the throttle position switch...had a coolant hose split and spray coolant on the connector to the throttle sensor. Next, I have found 2 bad injectors I beleive, those will be replaced next. Distributor has a little freeplay, but after replacing the rotor and cap it seems fine.
