    idle trouble HELP

    i just put in a cobb sri and a turbo inlet pipe, now my car won't idle. when i installed the inlet pipe the 1 i bought was poorly designed so i couldn't reattach the bov hose so the stock bov doesn't recirculate now. i disconnected the battery for 30 min while i put the intake on. when i started it back up the idle jumps around from about 450 to 600 rpm. when the car is moving its fine. Ive tried looking on some other threads but I'm forum illiterate. I know the ecu needs time to relearn but i don't know if i reset it. how do you reset the ecu and how long does it take to relearn? Any help would be big help.


    Thanks

    It sounds like you have a massive intake leak unless I've misread your description. The BPV hose being off would account for this, although the intake or the inlet would also explain it. Check your plumbing for a leak. If the BPV hose is off, fix that and go from there.

    You can reset the ECU by disconnecting the battery if need be.

    Since you say you are unfamiliar with the fora I'll leave this thread here (it should be moved to general troubleshooting/maintenance) so you can see the response(s).

    Thanks
    did you reconnect the breather pipe?? the car will run once it has the accelarator pressed but will cut out when at idle if the breather pipe is not connected.
    hope this helps!!

    if your recirculation hose isn't hooked up you may want to look there
    I work on vehicles that make 650hp and 2400ft/lbs.

    That'd be a horrible coincidence. The problem came up when you installed parts. It's reasonable to expect the problem to be related to that installation or those parts.

    ya thats what i was think then i started doing a little more research but the idle is to high for it to be that. mine is starting to die on me if i let it idle and when i push the clutch in the revs drop almost to 0. i need to get that bad tube out NOW. anyone know the part number for the hose that runs from bov to the inlet tube
