Searched but didnt really find useful info and the situations differ from what I am experiencing. Well whenever i drive on the freeway going in and out of vtec or being in vtec for a period of time the check engine light comes on naturally I checked the oil and it was full. the light only comes on when im at somewhat high rpm's not normal driving I can rev on it and take it to 7k or so and nothing happens no light but going in and out seems to **** something off and it throws a code. im wondering if my vafc is doing something. when it came onit would idle at 1150-1200. what is going on
car specs 96gsr I/H/E vafc-2 111,xxx miles
