Finished with 1978 280Z 2+2 restoration--but the engine hesitates on acceleration. When the revs build, it operates normally--acceleration is good. Injectors cleaned, fuel tank cleaned--no help. There is no carbon buildup from a rich mixture--plugs look good. Starting--sometimes fires right up--sometimes hesitates to start. Where to start?
Distributed. Plug wires..
Very nice old car u have there...
Check air filter and clean throttle body add Lucas Fuel Injector Cleaner to gas tank. I read were you cleaned injectors but the injector cleaner will also clean the intake and exhaust valves.
Coil check as well..
I have heard of fuel injection problems on those before- good luck- I have not heard of anybody ever figuring it out-
