when i was finished my front mount set up...i let the car idle for about 10 minutes with no problems. moved it, let it idle again for about 15-20 minutes. no problems. then one last look over for about ten minutes of idle. everything was good and idle was steady at 900.



then when i drove off, i pushed it very little to about 6psi and the rpms shot up to 3500 when i let off and was boucing back and forth from 3500 to 4000. i pulled over opened the hood and the rear rotor must of been EXTREMELY lean cause that part of the manifold was glowing red.



the only thing i have different is the vacuum on the BAC (the large opening one) is just open. before that it ran to the top mount intercooler piping. can i cap it, or i have to run it back to my intercool piping. or can i just block that bitch off. or maybe this isnt even my problem........????? when i plug it it dosnt fix the idle...maybe it has to calibrate itself or something.....





oh...and i have the older greddy type-s blow off valve. theres 2 vacuum ports on it. im only using one. could be another problem???



oh...if i put it in gear, the idle drops back down. and a soon as i take it out of gear, it shoots back up again.
