Hey, my first post in this forum, i've search on the forum and can't seem to find one tread that relates to my problem I'm having with my 96 SC400.

For the pass two times coming home from work i decided to have some fun on the freeway, and after the first few second like maybe after 5 seconds of WOT, i start to smell this weird smell, i can't exactly pin point where it's coming from and how it smells. What i do know is i have my vent's close from outside air coming in and all my windows close. i thought it was skunk or something but these happen at two differant spots same smell. Anyways, i know i'm not giving much details to this problem but seeing in any other SC owners out there has experience this problem before Thx..

 

Moldy cabin air filter?

 

Maybe your catalytic converter(s) are at the end of their useful life.

 

I dont think it's that cause when i use my a/c or have my diverter doors open, it smells fine...=)...

Hum...that could be a thought but the car only has 58k on a 96...so can it really be cats?
