Do you have an aftermarket cat in there? If you went anywhere other than the dealership, or called around for estimates, then they may have given you the cheapest aftermarket they could find to compete.

Most cars are fine for many years with an aftermarket cat, but I wouldnt be surprised if the Cobalt rejected one.
I would get a high flow performance cat, personally. I cant wait for mine to go! =D

 

Ok thats it get your car down here, I'm pulling the tune so we can see what is going on in there!

 

Go catless and never have that problem again.....

 

second stock cat on here

 

ohh hmm thats odd. I would never go catless though. The illegality of it and constant CEL would drive me nuts.

Just get a quality high flow cat.

 

What were you racing?

 

::scratches head::

uh. no

 

iam in Fl i really dont care bout goin catless anymore lol its driviin me nuts

the guy told me it was a GXP supercharged? i dunno all i know is it was quick as ****

 

which gxp?

grand prix?
g6?
soltice?
bonneville?

 

gtp maybe?

 

It was probably a Grand Prix GXP that was supercharged.

 

grand prix

 

gxp grand prixs are NOT supercharged.

5.3 liter v8

 

he said it was....i didnt see any badging....

 

GTP is the only supercharged one I'm aware of. Have a co worker who owns one.
Would of said GTP and under that Supercharged on the side of the car near the front wheel well.

 

i w
s lookin maybe he ment to say GTP...or i miss understood him i dunno

how much power do GTP's have??

 

area is correct----> gxp is a V8

 

260/280...with a few mods they can be in the 12s easy...they have no intercooler though, so their IAT2s are insane

 

what he said
