just swapped a b18b into my ek. the motor idles really low when cold and when i get off the gas. sometimes it even cuts out. my car was sitting for about 5 weeks so at first i thought it might be the old fuel. i have been thru 2 full tanks of gas and an octane booster to see if it might help. It didnt seem to work so i replaced the fuel filter. It still idled weird. My check engine light was on so I check the codes. only one code came up it was the throttle pos. senser. the motor is a -00 and i am running a 96 teggy ls ecu. I also tried my -96 civic ecu. Nothing seems to work tho. Im stumped. Any suggestions?
