I put a newer 02 short block in my 98 T/A this weekend, I also put in a 03 LS6 cam and some 241 cast heads over the 806's

Now the car idles like crap in drive, and surges alittle. Sometimes it wants to die. It had thrown a ses light for a 02 sensor but has since gone out, but the car is still funny.

I know the car needs to be tuned, but is it supposed to idle this bad with a freaking ls6 cam? I have to wait a little bit before I can have it tuned as I just spent a fortune having the motor installed.

And yes, the cam gear and crank gear were perfectly lined up so I don't think the cam is out. Car runs real strong, just idles like ****..

Im surprised as well. Really the LS6 cam isnt all that big. A tune can only help, but I cant see it driving that poorly.

I went from a stock 02 F-body (i mean truck cam) to an 03+Zo6 cam and ported 317's My idle hunted for a while but soon settled in. It probably more to do with it being A$ instead of M6. If you drive it around a little does it seem to get better?

nope, I drove it home today and its searching for idle. Sometimes it gets close to dieing.. and did die a few times crusing in the parking lot while turning.

Not running as bad as my old roomates untuned f-13 car or anything, more annoying then a real problem.

It ran perfect before the swap. Im running a bone stock 98 tune, minus some changes in the trans tables.

I have a feeling one of my o2s might be bad, but the light has gone off.. damn 98 pcms

Do you have any tuning software? Add some air to the desired idle air flow table and it will smooth out the idle surging.
