I recently used 87 OCTANE gas in my car for one fill, but now i filled back up wit 93 OCT, but when i change my oil I used 3 1/4 quarts of oil and 1 quart of lucas oil stabilizer. After flooring the pedel when i come to a stop I smell a stank *** egg smell can anyone give insight, is it my cadalyc converter going?

 

that **** stink people come on help help!

 

rotten smells are usually related to bad catts.

 

Yup, bad catalytic converter. Go get it checked.

 

0707 CEL code

 

u need a new cat

 

The egg smell !! 87 OCTANE will cause that prb an it has been mixed with 93. Drive it for a week with 93 if its still doing it it mybe the cat.

 

Wierd, never happened to me.

 

Use up all your old fuel in your gas tank and replace with 93 oct. If you have the same problem, your cat. is probably going bad. Get it check out at a muffler shop in your area.

 

Hey, I have this code, but I thought the problem was just the o2 sensor. However I also have the bad smell and my gas mileage is terrible (under 200 miles to the tank). I'm guessing I should change both the cat and the sensor? A new converter at autozone is $150 , would it be a bad idea to pick up a used one from the junkyard? Thanks for the help.

 

I dont think junk yards are aloud to sell you used cats

 

definitly need a new cat. the smell is the catalysts melting and breaking down inside....get a new one

 

yewa when i had a conour this was the halmark of a bad cat... it was a rotten egg smell.. it was mad gross. the new cat will get rid of the smell and increase gas miles

 

... NEW cat is BIG BUCKS... this would warrant getting the CATTMAN catback from the Ypipe Back.. = )

i know mine is comming to that point soon

 

Get the Cattman Fast Cat...It's EPA certified with lifetime warranty..

 

when i ran no cats, the smell was never THAT bad, but i have hurd that is related to a bad egg smell,
mabye get some bacon to level it out?

 

junkyards cannot really sell exhust parts.....

my dads max had that egg smell from the day he bought it brand new.....now 110,000 miles no check engine light or anything
