it also means your car is dumping too much unburned fuel into the exhaust,
probably oxygen snesors

Funny thing is, it only seems to happen on DOHC engines. I just rolled over 129k yesterday and still haven't ever had the smell. I don't have factory exhaust anymore.. but I still have the stock cats at the end of the manifolds!

My first mark had around 120k when I sold it, smelled rechet everytime I hossed on it. (everyday)

Hmmm, I might need to pick a couple of o2 sensors up then. No CEL on but don't seem to be getting great gas mileage either.

Posted by: turborich

How long do the o2 sensors generaly last for? Where is the cheapest place to pick 2 up at? Thanks.

Lmao more import kills to come, lol. Speaking of whooping imports my friend in his 96 lumina with 4 ppl almost took a civic with a noise maker it was close but come on 4 ppl in a 4 door base lumina haha. But im going in soon for a front end alignment, when its up im gonna have tips put in and 2 cats guted? I have the option to have the 2 small ones gutted and the resonator removed, but would a 3rd cat along be enough back pressure? How meen would my car sound with just a 3rd cat lol, what gains would I see hp/trq wise?
