I have a 1990 Integra LS with a 94 LS engine in it. All I have done is CAI, Exhaust, Headers. After being in the car awhile it starts to sputter whne i press the gas. Its ard to describe. Its like I push hte gas and the power is really weak and starts making this open header noise then once i feather the gas it will go back to normal. My pcv valve hose isnt hooked up right could this be why it is doing this? Any help would be greatly appreciated. Thank you.
