okay....ive got a 96 civic dx...y7 enigine still....and my car had sat for sometime and now im driving it again and its reving funny
it keeps reving up and down...couldnt say what RPM's cause i dont have a tach hooked up..but its real annoying and i think it chewing up my MPG...what im thinking is that ive got some sort of a vacuum leak or something...even for specifiac i think its my MAP sensor that has gone bad......idk....i need to get another one the be sure....
