i just purchased a 1993 z28 camaro. the engine was rebuilt a year ago. the car has been sitting close to a year. this car it pulls strong but when i am taking off it stumbles has if the car is shaking. if i floor it it smooths outs and stop shaking. i was wandering do i need to but spark plug and wires in this car because it been siiting for a while. any suggesting would help. thanks

 

Is it new or year old gas in the tank?

 

CHeck your plug wires and vaccume lines. If its been sitting a while, it may have been occoupied by animals which love eating crap under your hood.

 

well as far as the gas the car was on e when i got. i added some stp fuel injector cleaner to it and fill it up. i do remember the guy saying that he had the engine professionally cleaned. so i am hoping these so call professional did not get the wires, spark plug or worst the distributor wet.

 

If they did, no problem.. Take off the distributor cap, wipe it down and should be fine. Getting the wires wet is no big deal.
