Hesitation from boost to Vacuum..help
Monday, October 02, 2006 6:54 PM
Hey guys,
well, the s/c cavy is having a major hesitation when on the throttle say 2/3-3/4 and it starts off at about 4-5psi and then drops to 0 vacuum (accelarating with the pedal still at 2/3-3/4). When it his 0 vacuum, the car hesitates really badly. Almost feels like a govenor..revs won't climb anymore. When i go wot its not as noticeable, but i think its still there. I've tried running a bit rich, and lean,.. no difference. Looking at the log doesn really tell me to much either

Anybody have a similiar problem? Just pulled the plugs. They look pretty much normal. GOing to try to throw a new set in, but don't think its going to make a difference.

Thanks
Nate

go over all the vacuum lines on it there has to be a vac leak somewhere.

no vac leaks. At idle, i'm at about 21-22 in vac. 23 when cruising. I checked over the lines... nothing leaking
