RE: check engine light after A/C delete

Did you remove the Wide open throttle A/C cutoff (WAC) relay?.....if you did you might be getting a code 67 registered by the system. Do a KOEO self-test codes scan and LUK, you might have to reconnect the relay back so the system "sees" it's there....or place a 10 ohm resistor so the system thinks a relay is connected.
