I have a 1986 camaro and I get horrible gas mileage and the engine boggs down has carbon build up, and has a hard start. I ran the engine codes and I got 21,22,41,42. I also took all the pollution out of the car. I think it's the distributor and carb. Can anyone clarify this?, or tell me if I'm wrong. Thanks

 

Has you car ever gave you any problems in the past by anychance.
I myself would check out the carb and see that everything is to factory spec. If the carb need a rebuild I would rebuild it. And on the dist. i would clean the spark plug check dist cap, rotor, and coil. Relace it if nessasary After doing that i would check the timing and set it to factory spec.
Thats what i would do, not sure if you would like to do the same
