Today I noticed that my Speedo dances/bounces when my car is idleing to about 5-7 MPH and I've noticed that when I am braking or rev my engine, my rpm's drop down and then come back up and seems to be idleing higher than usual (almost 900). I recently put on a 70mm MAF from a later model SC on (mine is a 90) Could this be causing the problem?? Any other suggestions?
