Not only I noticed my car's exhaust smelling a lot like fuel, but my friend with his 95 Z told me the same when he was riding behind me two days ago. Is this a commun problem when installing headers?

 

I wouldn't necessarily say it's a "common" problem, but you could consider getting a tune. You'll get more power out of your headers and it could clear up the rich mixture a bit.

 

idk about if itscommon toinstalling headers. Butcheck your o2 sensors if youve smelt the gas smell before the headers.

 

spartan seriously, where do you get this stuff? how about an endoscope and check to see if you have any polyps on your exhaust? they may be cancerous if your car is having trouble peeing[>:]

the 02 voltage is nota rapid fluctuation. its oscillates a little slower than 1 cycle/sec typically. if your voltmeter cant keep up with that.... well, screw that. it can. at that point its operator error

 

k. This is where i got the info:

Now that's funny. Now I didn't catch if you had dropped your cats as well or not? And I didn't catch if they're long tube/shorties or midlength? Just a couple of things. Did I miss that? O2 sensors can do all kinds of things. If you have cat's and your O2's are bad you'll get a foul rotten egg smell and that's also an indication of bad cat's. I hope someone corrects me if I'm wrong but I'm pretty sure that's right? Also, at WOT an engine will usually disregard the O2's behind the cat and let the engine run a little rich. I'll see if I can't find where I got that, it may be in one of my "tech magazines."

 

I installed bbk shorty headers, had a new cat welded on, andmy car just died on me today. I was coming home from kragen, from pikin up the O2 sensors and my car began to hesitate a lot and woud'nt go pas 20mph. if i tried going past 20mph, the car would just back fire with a bad hesitation. I managed to drive my car home and now im waiting for the car to cool off so that i can take the old O2 sensorsoff and install the new ones.
i will post later on today what happens

 

also listen for an exhaust leak. it will sound like a tick tick tick

 

really? Sometimes when I floor it everynow and then it smells like that, is that what that is? (I drive a manual if that matters to any kind of smells at all.... i mean, Im pretty sure it not my clutch)

 

Thats what mine does, doesnt do it all the time but sometimes ill try to accelerate it feels like im pressing the pedal while the car is off for two seconds then it picks back up again and it has no power cruising unless im on the freeway with the pedal down a bit.
