ok i just installed a LS6 intake on my car with the egr mod and afterwards now my car surges and idles at about 1100 rpm...i know this usually happens if you have a air leak somewhere but i have checked everywhere and i dont see where it could be leaking from..I also installed a ported TB so i dunno maybe that could be causing it..so has anyone else experienced this??

Put your stock TB on and see if it stops. I'd check to make sure the IAC o-ring is in place (top plug on the tb over on the driver side.

Not sure, but it's common after a throttle body install, which if I understand correctly you did at the same time.

Usually the computer will relearn the idle after some time. If not, you can try the 'manual' idle relearn process, search for those terms and it should come up quick.

surging is not what is supposed to happen after an intake swap.

Ummm...Yeah. Agreed. Check to make sure you dont have your throttle blade stuck open, or any leaks where you installed the manifold.

adjust the screw on the ported tb if it isn't the same one that was on the car before

o ok thanks guys..i am gonna put the stock throttle body on to see what happens..the ported one i have is just a stock ported one though. oh yeah i forgot to mention that it seems to get worse once the car heats up...when the car is cold it doesn't surge and idles normal but once it heats up the idle gets higher and it will occasionally surge

if that is not the problem, then you have a vaccum leak.

well i put the unported TB back on and now the car is back to normal..i tried to search on how to do the manual idle relearn process but nothing came up...does anyone have a link or something to it??

+1 for vacuum leak. It happened on mine. I replaced the tb gasket and the problem went away...

ok i found the relearn process so i am gonna put it back on and see if the car can relearn the idle..thanks for your help guys

Im also gonna say vacuum leak. Is your PCV setup still installed?

Did you check to see if the O-ring was in the IAC on the new TB?

quiet_storm98

iTrader: (48)

yeah it is still installed but after i put the stock one on it is fine now..i am gonna put the ported one back on today and see if the idle relearn process will help..by the way what part of long Island are you from?? My bro lives there and i was born there so i visit there sometimes

umm it looked the exact same as my stock one but i didn't really notice, i will check today

quiet_storm98

iTrader: (48)

i didn't really look but i will check once i put it back on today

quiet_storm98

iTrader: (48)

ok i checked everything when i put it back on and everything looks fine..i also di the idle relearn procedure and the car is still not idling right I have no idea at all why...i dont see where it could be leaking from or anything so i guess i will just throw the stock one back on again

im picking up a ls6 manifold this week hopefully, did you notice an immediate difference after the install?

Thanks

yeah it had everything..i did notice that the hole that feeds air to the IAC sensor is smaller on the ported one though because there is a piece that covers that area on the ported one so i believe that may be the problem..i am gonna try to get that piece off and bolt it back one and see what happens..but anyway my Bro lives out in uniondale so i dont know how far that is from you..he also had an f-body but had to sell it for financial reasons
