Ok I'm running a 1993 VTEC, auto trans, with an F22B1 SOHC VTEC that has been modded, and for some reason my Check Engine light is always on... the only thing I can figure out is that, when I bought the car, the girl told me the ECU had been changed out to run the VTEC Controller, from APEXi...
of course I still have to change the solenoid, cuz my VTEC isn't even kicking in right now... so is the check engine light problem (which I'm guessing logically) due to the ECU and VTEC controller trying to run the VTEC, which isn't connected?
Oh and which ECU was swapped in to run said VTEC Controller?
I'm taking this info to my tuner to get retuned, and I'm gonna put it on the dyno...

 

Take the car to Autozone, have the CEL code pulled, reply back with that info, then you'll get some answers.

 

dude he has a 93 autozone cant hook a machine to it.... he needs to pull the blue 2p plug from the radio near your feet and put a paper clip crossing the two wires over and see what codes you blink out... 1 long blink is 10 and shor blinks are 1 for example you get 2 long blinks and 4 short blinks that would equal out to be code 24 very simple
