i got a automatic 94 z28.
today i went to start it and it hesitated really bad then finally started up.
when i started driving, it was really rough, like it was having trouble accelerating and it just sounded rough. spark plugs? any suggestions would really be appreciated. thanks

 

burnt wire, bad iginition coil, bad plugs, bad opti, bad maf, stuck injector, etc

the list goes on and on

scan it or start replacing cheap **** then go from there (i.e. - plugs)

 

Is there an SES light? Almost sounds like an engine misfire. As suggested, check over plugs and wires for starters. Also look for any obvious vacuum leaks.

 

brand new ignition coil, new optispark, new wiring. but i just found out my radiator needs to be flushed, would that be the reason for the roughness? and my engine is ticking.
