Allrite on my 01 LS the check engine light came on and then the car started revin and shit...You think it idles like most integras in which the RPM goes up and down but my doesnt go up or down...it just stays at 1,500..It got an intake and exhaust on it and some pulleys...anyone know what the problem could be?? one of my friends said it could be the MAF sensor or some like that??
