Ok after I installed the entire exhaust (rb header presilencer y pipe and mufflers) I start my car and it will either do a cold start rev, hold at 4k and then drop, splutter and die or start rev to 2.0k and then drop and die. I might have an exhaust leak between the header and the presilence because i need a new gasket. I have removed the ACV its sitting to the side, the port actuators are back on, the o2 sensor is back on I have ran a rubber hose from the split air pipe after i cut it off to make it shorter and ran it into the backup pressure bung on the rb header. I tried adjusting idle and afm and nothing different really happens. Could the exhaust leak be causing this? does everything seemed hooked? because the acv is gone and the airpump is still there? I am trying to figure this out before the weekend is here. I will be checking so please reply

hang on is the ACV blocked off or is it just sitting off of the engine???

its open right now, I havent made the block off plate but by what I have been searching that would cause a vaccum leak which explains my horrible idle...am I right? also by what i have searched I no longer need the air pump and i can remove that and cap off alot of tubes

i would either reinstall the ACV untill you get the block off plate or it wont hold idle...it will just keep shuting off. and yes you can remove the airpump and cap everything off....thats very easy...i did it in about 10 min at max....

awesome as for the split air pipe, I cut it off after the tiny tube that i think goes into the actuators and routed the end of it into the backup pressure in the header...does that sound correct
