- Sat Aug 11, 2007 3:36 pm #19436 yeah 5500 is about the exact RPM that vtec begins at. so does it misfire at 5500, stall, or just bounce the tach as if there was a rev limiter?

- Sat Aug 11, 2007 9:58 pm #19467 with the engine off, have someone sit inside and push the pedal all the way to the floor. then you watch the throttle body and when they have the pedal to the floor, see if you can turn the TB open any further. may be the throttle cable or gas pedal needs adjusted.

I had to do this once, after I installed a different manifold. I thought my vtec was not working, and it turns out my throttle body was only opening about 3/4 of the way. (I didn't have a tach at the time) I was probably only getting up to 5k rpm

- Sun Aug 12, 2007 5:59 pm #19533 sometimes they get a little moisture in the cap and that causes the problem

Race cars are like boats I guess. Time to bust out another thousand.
