I first would like to say thank you for any helpful suggestions. 1993 Honda Accord EX JDM H22A Skunk 2 P13 I just got this car back after 7 years due to an accident. I attempted to engage vtec @ 4900 and it does not kick in. It was obviously noticable when I previously had the car. I drive 35 miles ...my check engine light turns on, and my vtec is now working. About 40 miles more the check engine light turns off and so does vtec? Whats going on?
