i bought a z about 3 weeks ago. its an 03 with 46xxx miles it is supercharged by stillins. stage 3. it surges like your pumping the gas at about 3 or 4 grand when driving.but if u floor it it ****in goes but dont pull as hard as it should. it has ran fine till now but it did set 6 months befor i bought it. any ideas? and also where is the fuel filter?

 

maybe the belt

 

sitllins? did you mean stillen? i might be wrong too

 

sounds like a belt issue but i'm not certain

 

ya sorry stillen

 

No, it's the bearing.

 

Or the gasket.
