Just Installed New 3 Piece Pulley Kit... I Have a Few Questions....
Well I just installed my New Rotary Extreme 3 Piece Pulley Kit and finally eliminated my Air pump.... the car runs great when it gets movin' but the idle is really lumpy....
the kit is the main pulley, water pump, and alternator pulleys.
I took a look at the commander on my power FC and the bar graph at idle is going up and down all over the place at idle.... this is very peculiar to me... before eliminating the air pump the graph at idle was fairly straight.... just wondering if this is normal....
I also noticed that my vacuum reading at idle is lower... i used to get about 15-17 vacuum at idle now it's only reading 10 after the pulley kit and air pump elimination.... i'm pretty worried about that...
needless to say the car is very responsive on the highway....
someone plese tell me if this lumpy idle is common... especially since I have a large street port... I just want to know what I can do to even it out a little better.... also what should I do about the low vacuum pressure...???
any help would be greatly appreciated...
thanks in advance....

As it relates to the hunting idle since I'm assuming you're underdriving the alternator now, if you have a lot of electronics the alternator may not be able to keep up. Although it could just be the Power FC readjusting itself
