ok,just swapped a b16 into a 93 cx hatchback. followed the step on wiring vtec and it worked for a day then started throwing code 21 and 22!! i re wired it and still nothing. what could cause these codes to be thrown? bad vtec solenoid?i have oil. im running a stock p28

get the rite ecu first off or get the p28 chipped.. using a stock single cam ecu on a b series motor is no good to start off with.. id start withthat first.. but may still be issues with it.

yes you must have a chipped p28 you cant just use a stock p28 the fuel curves and vtec engagement are not correct.
