I just finished installing my b18a ls vtec in my eg civic. I fired it up and it runs great but the CEL light will not reset. I removed the 7.5 amp back up fuse ( per the haynes manual) to reset it but it does not reset, the second I start it up the CEL light comes on. When I check the code the cel is a consistant flash. I checked the o2 sensor and when cold it is .7v and when the engine is hot it reads .7v no change. Am I missing something to reset the ecu? or is the o2 sensor bad? I Am running stock jdm 4-1 header, cams and pistons with a aem cai. I do not have the exhaust or the catalytic converter hooked up yet would this cause the code. Thanks I am also running a chipped p28 with the Knock sensor removed.
