I installed the ls6 intake.

Cranked the car and it idled alittle high for a moment. then it went down..almost tried to died but didnt (battery has been off for 4 days)

Took it for a test drive...seems great..added some power down low quicker acceleration and throttle response.

Now not evertime but it seems like at first when I would come to a stop the car would idle down (500rpms) I would tap the gas and it would go back to 750rpms and idle fine.

drove fine went threw a couple stop signs then a few minutes later at a red light it tried to do it again.

I can't hear any leaks of any sort from the intake all the plugs and hoses are on good.

Beside the idling which it did 3 out of the 20 stops I did it runs great and runs alot better, and actually before the swap I could smell alittle gas now I can't

Also when I would try and take off after it tried to idle down it kinda hesitated.

Each time it would try and idle down it would get alittle less worse each time. On the way back home it did not hesitate once.

Could the computer just be trying to adjust itself to the new air flow.

Once again no problems during cruising, or wot.

Changing intakes,

isn't going to affect idle on the car.

It sounds more like something didn't go back together properly on the car.

^ See if you can rent a Tq wrench or borrow one from a friend. Did you mention before you didn't have one? I'd almost blame that.

Did you switch TBs? New plugs at all? (Just curious on the plugs) Hesitation is normally ignition related. Mine ran fine after the LS6 install. Plug in the small HVAC line in the back of the intake? MAP sensor back there too?

I'm thinking you've got a leak somewhere, tho.

Yeah i can get a torque wrench may have to go back and loosen all the bolts on the intake and redo them. I just tightened them down to the intake then went around and put a good turn or too on them, nothing super tight...just can't hear a leak though...I can hear my tensioner squeking.....another thing

Everything is plugged in..all the lines are secure no leaks so it's prolly the intake. I changed tb's and the tb has a longer runner on it where the cable goes over.

I just went and drove it again acted fine..didn't hesitate one bit.

This is a video I took after driving it awhile..pulls descent for a 140,000 mile car I think.

im going to bet on the TB not setup correctly

How would it not be set up correctly...everything is like it was..I double checked.

Like I said it only did it 3 times and only really within the first 15 minutes or so.


Is there any differance at all between the TB's that came on the ls6 intakes? and the ls1's I was told there wasn't

Did you disconnect the battery? Sounds just like standard computer re-learn.

Changing intakes will not change the idle of a car but... if the intake didn't seal properly it can. Had a similar problem when I first installed my Super Vic. it didn't seal properly to the head and was allowing extra un-metered air into the engine. This caused the A/F mixture to bounce around. The O2 sensor saw this bouncing A/F and adjusted the timing and fuel which made my engines idle oscillate between normal and low.


***Edit- More than likely you don't have this problem because of the different gasket design. My super vic uses an actual gasket to seal between the intake and head. Whereas your LS6 uses the standard rubber o-ring type gasket that is a superior design and is less prone to leak. It is still a place to look though because it is a possibility.***

Yeah battery was disconnected for 4 days when I was waiting on the oil pressure sending unit to come in.

Like I said pretty much after 15 minutes of driving it was running good and hasn't done it again.

I'm just paranoid about stuff like this.

I once had a 2000 chevy took 7 days to put a lift on due to missing parts.

It took about 2 hours worth of driving before it would act right again.

Update:

car acts and runs fine...no more hesitation or anything.

No there is only a loud squek a very very loud squek...not constant.

I can get in the car after it sits for a hour or two and drive it..nothing..but lets say I'm getting on it alittle and the rpms stay about 2500 for a moment this loud squek and chirp comes from the engine bay.

I believe I have a pully or tensioner, or a water pump going out.

Do a search on Idle Relearn Procedure

Also, the car will relearn idle on it's own after a few driving cycles and stop/go driving. I did my LS6 intake swap when they first came out, my car was idling strange until I did this relearn procedure. Of course if I would have continued to drive it it would have sorted itself out.

Thanks for all the comments guys...car runs great...it was actually the idler tensioner...found that out when it seized up and the belt broke.
