Well I posted this in the EG forum and didn't really get any help. After finishing up the greddy turbo install and making sure the car ran fine, I changed to a 1 step colder plug. None of the shops in my town (auto zone, advance auto parts, etc..) had NGK in stock, so I went with Autolite. When the car is idleing, or if i floor it from like 1,500-2,000 rpm, it sputters like a go-cart. Maybe someone can help me out.

 

Make sure the wires are on all the way.

 

whats the gap at?

 

Pretty sure the wires are on all the way. Gap is at .030.

 

Noone else has any ideas?
