ok so i just found out that my stock cat is clogged. so i was wondering if i could gut it till i can get a new dp with a cat in 3 weeks or should i leave it as is and just replace it in 3 weeks? and if i gut it will it affect my gas milage? it is all stock and pushing 15lbs at wot... and i know stock psi should be 12.5 at wot.

 

They just had a recall on the 05-07 sc cause of the cat.. take it in and they will replace it for free

 

ya. dealer should give u a new one for free. i just got the recall letter the other day. i just laughed bc i just put on my catless dp

 

WTF!!!! so i took it up there this morning to my gm dealer and they told me there was no recall. she show me the recall on the car she print for gm and and it said none! WTF?!?!?!

could some one upload there letter on to this forum so i could print it off and so the dealer that there ******* wrong!

 

Shyt i will ask my buddies if they have it

 

dont push your car with a clogged cat, be easy on it until you get it replaced

 

That dealer is full of ****. Even if they told you there was no such recall which there is by law if your cat is not working properly they have to replace it. Even if you warranty is up on vehicle emissions there is a seperate warranty due to emissions. I had mine replaced before this recall was out. I believe the warranty on emission effected parts is 8 years or 80'000 miles. They have to replace it by law!! The cat is part of the downpipe and I believe that part is around 600 to 800. Hope that helps you out.

 

im going in tomorrow morning to have a look at 98dollar foor that... but they said they cant just tell that, thats the problem over the phone and if it is it cover under an 80000 mile warrenty. but im not throwing a cel... so how should i explain it to them... "when at wot the car goes to 15psi and not the 12.5psi it is so pose to be at stock"??

 

you sure you didnt get the recall notice in the mail? lol

 

yeah, nearly everyone, including myself got the recall on it. you should have too.

 

Call GM and have them send the dealer a heads up about it. The dealer should know about the issue, but it appears they don't.

 

no i havent i just bought the car on 1st of this month so... i called gm and they said couldnt tell the problem over the phone to have the chevy look at it and see whats wrong. i have a gm caller service number so if they dont find the problem at the dealer to call them back. gm never told me over the phone that there was a recall for it...

 

Yep theres a recall.. Maybe they just replaced it if u just bought it?
Look at ur dp when the car is on.. Is ur cat starting to glow?

 

I don't think it was a full fledged recall (I never got a letter, I havn't had the car long enough... plus mine was replaced about 3 monts prior to me getting it), but rather an exension of the cat warranty.

 

ok i check the cat after 2 wot runs at 15 psi and it wasnt glowing red hot it had a temp of 345-616 on the out side metal tho temp were al taken from every point on the cat using infrared thermometer. lets just say the cat isnt clogged. what else could make the supercharger over boost to 15 psi?? a boost leak??? could the boost gauge just be reading incorrect?? im not trying to spend 98$ tomorrow for them to look at it and say nothing wrong when something is...

 

Could be the guage.. Alot of people been messing up lately.. or ur Boost solenoid could be stuck in the closed position.. turn the car on and have someone rev while u watch the black solenoid on the Blower.. does the lil hinge thing move up and down?

 

so i put my code reader on it and its not reading any thing. the solenoid is working. but there is a light that looks like a car with a lock going throw it on now... any other thing you guy can throw out to me to check or explain why im pushing 15 psi on a stock pulley?

 

Thats the theft system.. dont know why that woulod be on.
And hmm.. if anything man just gut it to see if that fixes the problem.. maybe its barely clogging?
Cause the recall says it would throw ur car into limp mode if it was clogged

 

but would a minor clogged cause it to go up 2.5psi???

as far as a supercharger can it have boost leaks that would cause this??

but 2.5psi for a barely clogging... could it have a boost leak thats causing this?? could it be because i ran 87 fuel instead of 93???

i took off the bottom vac line on the supercharger to see if that was the problem and it didnt nothing.. still pushing 15 psi.... im so lost.

 

Only thing I can think of. If it still vaccums normal I would so no leaks

 

k im going up with the letter of the recall for the cat that i found on the forum my vin # is in the listed numbers so im going to show them that.

 

Let us know how it goes

 

ok i took it up to the dealer and they said every thing was operating as is and nothing is wrong with the cat. there was no charge to me. but yet im still boosting at 14.9 psi. i talk to another mech. and he said the dump valve might have a weak spring or something wrong and suggest i replace it myself. so im going to do that... what type of boost gauge comes stock in the ss/sc ta mechanical one or eletroncial?

jw whats the part number for the bypass valve type it in the search and couldnt find it..

could it be since the temp around here are 30%-46% that im taking in cold air causing it to boost more???
