Hey guys have the injen cai for the ss s/c with custom 3 inch exhaust and I had it dynoed the other day and around 5700 rpm the car starts to run lean I was wondering if anyone else is haveing this problem or is the intake sucking up too much air. In cas you are wondering my a/f was arond 13.5 when this started to happen. And one more word of advice do not by the spec stage2 until it comes with a replacement bearing and allignment tool becaue it makes funny noise at start up like a clicking, and if you press the clutch in too far it makes a funny noise can't describe it, and the install was right.

 

That's very lean, what where the dyno conditions?

 

I wonder if you were running lean prior to installing the CAI..?

 

I heard the Wideband sensors that they just hook to the end of your exhaust read almost a point off....meaning if it read 13.5:1 your really around 12.5:1

 

You heard BAD info. I have a wideband on my car right in the downpipe, it was with in .2 of the dyno's!!

 

please post the dyno sheet

 

 

same here buddy got my car dynoed and i was at 13.1 to 13.4 air fuel. Thank god i didn't get the 2.8 pulley my motor would be getting owned right now. but i don't even have exhaust yet. Oh yeah im an 05.

 

hey just got back from work will post the dyno sheet tomorrow and i have a side by side with another cobalt from that dyno with just exhaust and he is running almost flat 12 all the way. by the way ran a 14.5 last night with a 2.3 sixty foot and running lean. P.S. The dyno is only a month old and it is top notch all wheel drive dyno.

 

my car is doing the same thing stalling and hesitating at high rpms. mine says system two lean bank 1. i think it might be my injector anybody know what it would be

 

That clutch noise happened with my spec stage 2 clutch as well didn't think too much of it though. I talked to spec and they explained it was "high spots" on the friction plate and that it would go away.

It still even made the noise after 500 miles of wearing in the clutch. Then recently i raced against my friend's Trans Am ws6 to see how my SS could hold up, and the cheap clutch just ended up slipping uncontrollably coming out of adjustment. (i thought i glazed it but i barely slipped it myself if at all while racing) Also, that noise happens when i push the clutch pedal down normal amounts and i only need to push the pedal down an inch to fully disengage it. SPEC just better be willing to replace my faulty clutch.
