new to the site and just wanted to know if anyone knew what i can do. there is a 94 z28 for sale and it has a vortech charger on 6lbs. the guy says there is a misfire when the car is in full throttle but other than that the car runs fine. i was thinking the gap in the plugs or it needs different plugs. please help thanks.

 

I had a car do the same thing. I installed Tr6 gap them at 36 and still had a mis in boost. I regap them at 30 and the car ran great.
But still the car your looking at could have something else wrong.

 

buy it Kevin stop being a little bitch and buy the damn car....j/k ive seen that car b 4 its a pretty clean car..but becareful he has supercharged it for a reason...to be faster and hes from where we are so he most likely raced it..just my .02
