Cammed idle issues
 

Other than the obvious lope, my car almost stalls out when Im sitting at a light, it used to only do it cold but its doing it all the time now. The RPM's will dip to like 300 then bounce up to 1200 and it just cycles like that or stalls until I go, also when I first start the car and drive it almost stalls once then its fine. I dont get whats wrong TPS issue maybe? Idle tune?

Well... what the cam size?

Cant really tell anything without datalogging it.

I would datalog it but I dont have any equipment. Couldnt tell ya cam size, the paper work I have just says Billet core ls1 camshaft, but it has a nice lope to it. Basically what Im asking is there anyone with a cam having the same issue. Im having my tune looked at soon.

A small cam on a tight LSA could have a lope to it...

Datalog with a scanner or such, see what the TPS is reading, IAC, could be cracked intake manifold cuasing a leak, a bunch of things

Sounds to me like the airflow values in the colder temperature range are too low. Take it back to your tuner he'll have to adjust the idle airflow values for colder ECT values. I could also take a look at it using a scanner if you want, PM me if you are interested.

I bought the car this way in MD so there's no taking it back to the tuner. If my manfold was cracked wouldn't it cause other performance issues off idle?

It would be most noticeable at idle. I could take a look at the tune and do some logs with a wideband. See if we could tell anything from the logs.

Then if you want I could do a full tune for you with a wideband for you for $200.00.

IF you want to take a ride up to NY give me a call. We will put it on are 224x dyno jet and do a full tune. No street tuning here
