i am driving an 04' procharged z (touring) and i had this smell out of my exaust and some people have told me its my cats. Now my car started missing , so i thought it might of been a fuel problem because i just had some fuel issues. But anyway i made it a liitle fat on the bottom end and now i think i fouled a plug or two. also my check engine light, vdc,and slip light all came on. and before i did this added more fuel i took my mass air off and cleaned it, with carb cleaner. i dont know maybe im an idiot? please help.


thanks

 

oh sorry if i put this thread in the wrong place. Im new.

 

Pull a plug. If it's white, you're running too lean (= bad). If it's black, you're running rich. Remove all plugs, clean w/ carb cleaner, and get a tune.

 

i didnt think these cars worked like that. I thought when you let off the thottle the computer throws a bunch of timing in to burn the gas still left in the cylinder. so you cant go by reading the plugs. And also I hooked up an LM-1 (air fuel meter) to it before all this and it had a great A/F

 

Think you made it worse when you sprayed Carb cleaner on the mass air sensor. I remember reading a thread in g35driver about someone damaging their sensor by sprayin cc on the sensor.

 

Did you ever get it figured out?

 

is it an egg smell??


if so , you need some high flow cats or test pipes in there.

 

^ +1...i was gonna ask the same thing

 

Egg smell??? Have you been reading Manifold Destiny?

Book Description
How many miles does it take to braise a fish fillet? Should you use your exhaust manifold or your valve cover for a pork tenderloin? Were Jaguars really designed with veal scallopini in mind?
In the new revised and expanded Manifold Destiny, Chris Maynard and Bill Scheller, two experienced rally drivers--and cooks--answer these and any other questions you've got about cooking under the hood. After all, why drive to a diner when you can turn your Chevy into one, especially when you can make a better meal right on top of your engine? With a little bit of ingenuity--and a whole lot of aluminum foil--you can whip up dishes like Cutlass Cod Supreme, Cruise-Control Pork Tenderloin, Nifty NAFTA Nachos, Donner Pass Red Flannel Hash, and Fupped Duck Catera.
Witty, preposterous, and great highway fun, the more than forty recipes in this cult classic are road-tested and taste-bud-approved. It's a must for anyone hitting the road with an empty stomach and a full tank of gas.
