Hey everyone,

As some of you know, I've been having issues with my car, what I believe to be the cat causing mega power loss after the car warms, I need to get this fixed. I've tried to pull codes, and no codes are found, however there may be a pending code in the system.

I can't take it to the dealer right now, with the 3.0" GM Stage II pulley on there. I unfortunately don't have to original either.

Is there anyone here who can help me in this situation? Either to put an original pulley (if I can aquire one) back on or anything else?

Thanks,

Sean

 

Did you put the 3" on without the 42 pounders?

 

hey pay for shippiin and u can have my stock pully

 

^^^^^ he beat me 2 it LOL

 

Has nothing to do with it, I've run like that for a year now, I don't beat on the car, it will boost fully and completely when first started.

 

I think your hooped.Gm won't cover you if you melted a piston.even if you put the stock pulley on they can tell what caused the failure.

 

If I melted a piston I would be blowing blue smoke out the back and wouldn't be driving around... I highly doubt that's the case. Read the original post.

 

**** gm, if you fart at them the wrong way they void ****....... and it takes em forever for em to fix **** anyway, ive been waiting a month for em to fix my hand brake.

 

True, being a warranty issue though, I don't want to pay.

 

you do realize that spaz and myself work at a gm dealership in the service department don't you?

 

lol wow that says alot..................... HAHAHAHAHAHAHA JUST KIDDING!!!!

 

That's awesome. How exactly does one drive around with a melted piston and not see blowby? Mr. Educated GM Service man?

 

uh oh, i dont like where this is goin......

*grabs popcorn*

 

meh... I've just heard stories of IDC of over 120% on the stock pulley, let alone a 3.0".



I know what you mean...
This could get interesting....

 

i have herd of that also i dont believe it though...... i saw somewhere that hptuners had a flaw in that area. i donno.... bah!

 

I think there is a flaw also in the calculation for IDC in HPtuners. I have logged my car using two seprate Histogram files and got two different readings for IDC. One was 90% and the other was just under 50%...hmmm

My scan guage gives 14-15 ms at WOT which equates to roughly 85-90% IDC with a 2.85 pulley.

 

Anything's possible, I have heard obviously otherwise as well as your statement but I believe it has as much to do with driving style and how the Computer reacts to it. Like I said, I really don't beat on my car, I'm very much a Grandma type driver with this thing. I really doubt that having my 3.0 inch pulley has harmed anything in any way.

I have however, observed a few cats going on these cars, and based on past expirence, that would be my guess onto what's going on. I won't know until I take it in though, we'll leave the complete Diagnosis to the people who warranty the car. We'll see.

 

I have had my car in for work at the dealership with my stg 2 .. they dont know the difference.. my car would not run when we kinda screwd the car up when tapping the shift light into an injector wire.. and they fixed it.. and told me there was a crack in an injector wire they didnt even see the shift light!!! i would say dont be scared at least ur car will run

 

I didn't say you had a melted piston, my point is gm likes to denie warranty whenever they can. They is a document with pictures of pistons and descriptions of failures that denies warranty


awesome. They won't cover my axle either.

 

lmao, why wont they fix your axels chris? HAHAHAHA

 

no Idea why they won't fix them. I think it is a factory defect.

 

just gut the cat and be done with it.

 

Ahh I see. Well, I hope in my case, that isn't the case. My claim is definately not caused by any abuse. It's a GM, can you expect anything more for quality?

I haven't had a good expirence with this car, It'll be the last new GM product I own.

 

LOL "Factory defect". I get a feeling they might see it a little differently.

Off topic here....but the Hurst shifter I picked up from "Spaz" is kick ass!! Thanks bro for putting the shifter in for me too!

 

Leafy, I have today and tomorrow off, if you can pop by some time I have my stock pulley kicking around which you can borrow till we can put your 3" back on.

As for warrenty, its amazing what a dealership is willing to do once you go directly to gm customer assistance. Believe me I know first hand.
