Found Vac cap off???
Yesterday i received my set of smoked headlights so i was so excited to put them on i ran outside and did...After i was done i wanted to check over a few things Guess what i found...in the back under the upper intake its A Trickflow street heat...there was a Vac cap off...How long it was off i have no idea...so i capped it and the idle went down so i adjusted that,and i took it for a ride and i have no idea if this was causing an issue but the PCV didnt blow out or the breather... car ran great,,the only thing i noticed was it would go a little richer quicker of course it would it doesnt have a Vac Leak now..idle is still perfect just like i said a little richer when getting on it..went into boost so it goes down to were it always did...I hope they didnt tune it that way or it blew off on me a few weeks ago...or something that is scary i have the car here today ran great..should i just keep an eye on it or what????? Also what are your AF reading while driving...car idles between 14.5-15.0 and driving it goes from 14.5 to 13.5-13.8 then when i hammer it goes down to in the 12's then in high boost 11's is this ok?
