Car still spits and spudders sometimes
 

My car ocassional still spits and sputters then I accelarate hard for a couple seconds and it goes away for a while, bad gass, new gas filter, new plugs maybe?


its a 98 Z28 with Grantelli MAF, Power Effects Exhaust TB Bypass, Air Temp Module Off now, some things else cant remember.


Any timps
