Ok like a week ago i put in the fields boxer vtec controler and it worked great. Last night i was driving home and my check engine light came on and it was running like crap. it was bogging and my battery light went on. The codes it threw a vtec solenoid, CYP sensor and MAP sensor. I took of the vtec controler and everything went back to normal. Has anyone else ran into this problem? I am pretty sure that i did all the wire correctly but im not sure about the VTM or some sensor thing. i dont know what they are i just followed the wire digram for it. Does anyone know what VTM is? Or what could have caused this problem?
