Alrite so here is whats going on... this started bout 5 days ago... when i go to start my car for the first time each day. Black brownish smoke comes out when i give it a shot of gas but after bout 30 seconds or less it goes clean again... now its not blue.. its like black kinda brown colour.. it only happins when its the first start for the day after that it never does it again till i start it the next day... Now would this be a dirty Exhaust or a clogged Katback or is it running to rich??? im kinda lost on this one... the muffler is stock one from 2005 when the car was first bought... so ya any help would be great..

 

Sounds like a bad cat. Also due to your car running real rich. Atleast my old lsj did.

 

Did you receive anything in the mail from GM? I think there's a recall on them cats

 

remember i bought this used bout 4months ago.. so my catback is probley clogging up then.. looks like im going to be playing tonight in the garage.. thats a load of my mind...

 

oh right, forgot about that. it probably is a clog in your cat

 

haha np dude.. i wouldnt expect u to remember that... maybe i'll have to get a new one..

 

Sounds to me like your cat is shot or on it's way out.

 

if i do need a new Cat.. whats a good place or site to by a performance Cat from... no stock junk for me...

 

I have a Magnaflow high flow cat. It Came with my ZZP header and dp.

 

LoL,
Mine's been doing that ever since I bought it. I just shrug it off. Did get the letter in the mail about the recall on the cat, But they are saying if there are signs of power loss etc to bring it in otherwise I have 10 yrs from manufacturing date or until my car hits 193,000km for symptoms of power loss to take effect. And for it blowing the smoke every morning when I snap the gas, I am far away from having power loss.

LoL. Kind of surprising, well not really, every problem someone else is having with their's I've had, or is having with mine. LoL
Great ol car.

 

Black Smoke is good.
Blue Smoke Bad
White Smoke Bad

Black smoke is normally caused from un burnt fuel in the system from your car running to lean.
blue smoke is caused alot of times from rings being shot
white smoke means you have coolent getting into the the motor where its not suppose to be.

out of the 3 i would be way more happy seeing black smoke, then again mine does it

 

mines does it as well it blows black smoke nothing new for these cars

 

Mine does this ONLY if I put gas in it from irving .. no clue why, but if I get my gas from petro can it's fine but get the gas from Irving and I get black smoke coming out the back ... lol

 

ya i find mine does it with mostly irving i find shell works the best

 

Shell V-Power is the only gas I put in "The Rocket" as my gf calls it

 

LoL Canadian Tire for me. That's where the gal works. She likes the C.T. money we get back. Hey Adam, ended up fixing that broken headlamp assembly. My uncle Redneck fixed er. But it's solid. At least this spring I don't have to worry about it falling out when I take my headlight covers on and off.

 

yea shell is all i use too my motors head looks like its brand new with 103,000km on it

 

haha same here shell v-power ftw

 

07MetallicSC - your gf calls your car the rocket too heh :P

Ryan - Good job, so you won't be needing my stockers huh?

 

Ya, Does the same thing when i give it a shot must be just normal like said above

 

Well not for the time being. Just as long as (For the love of God) one of my HID's don't burn out. (Shudder just to think of the cost of a new bulb for that) I should be alright. He placed some sort of slotted metal piece in there which attached the headlamp to where it originally was supposed to hook before is snapped. Secured it quite well. I presume if I ever got in a head on (Another shudder) that the only thing that would stay in place would be that headlight. LoL

Even though I'd still love to go painted black. <<<Good song. LoL.

 

Well Ryan just know that you can always try them out anytime you want. They're just laying in the garage collecting dust. I never tried them on my car, but im sure they would look nice with your HIDs in that "painted black" housing

 

Don't stab the gas when the motor is cold.
