need some advise,

i have a '00 trans am, has the ls6 intake, had a cam installed last summer and tuned. went with a stage 2 btr cam.

when i first got the cam installed and tuned i had an idle issue, car needed gas pedal feathered for about 5-10 seconds to get it to idle. after that the car ran great and idled great. kept thinking i need to get back into the tuner to have it sorted out. however the tuner lives a couple hours away i have never made it happen.
When the weather cooled off the car would idle fine right after starting.

anyway, the other day i drove the car and noticed it was idling high, i suspected vacuum leak, noticed the rubber line coming off the ls6 intake to the pcv was torn. Replaced the line and now the car will not idle! any ideas???
i can finally get it to idle after it warms completely up. I started thinking was this vacuum starting to leak when the car was tuned and now that its fixed the air/fuel is off. could it be the pcv is sticking? any thoughts ideas is appreciated.

 

I suspect it was tuned with a slight PCV vacuum leak already present, and now it's gone, so it's not getting enough air.

Try this -

1. Turn the set screw on your throttle blade 1/2 turn.

2. unplug the TPS and IAC. key on for 30 seconds, but don't start the car. Key off, and plug everything back in. this will reset the TPS after the adjustment.

Rinse and repeat as needed. if 1/2 turn makes it idle fast, just start working the set crew back down. Make sure you do the reset after each adjustment.

 

thanks i will give it a shot!
