I have a 93 z28 camaro. when you put it in rev. you can feel a slight miss like one of the cylinders isnt firing. then when you drive it you cant really fill the miss until going up hill or if you hammer it. it runs okay just doesnt feel like v8 power. anybody know what the misfire could be? just changed spark plugs and wires.

 

what about your opti.how many miles or how old is it.

 

Was this problem the reason for the plug and wire change or is it new? Check your wires at night it's possible the "new" wires are arcing and make sure the wires are going to the correct cylinders. It's really easy to get 2 switched! Does it miss at all rpm's under a load, and what plugs and gap are you using? A list of engine modifications could help.

 

yeah the spark plug and wire change i thought would fix it but it didnt. and i dont know how old my optispark is because i just got the car like six months ago and trying to get it running right before i start putting power adders on it.
