Maft is the same setup on the F-bodies.. Ignition Control Mods are nortorious for going out but you would get a missfire code or something along those lines.. I would start with a new air filter, new spark plugs, and a new PCV valve. Basically do a tuneup if it hasnt been done in a while. Its a good, cheap thing to do and who knows it might be all the car needs. If that dont work then at least you ruled out the maintance stuff..

It gets its maintenance, air filter was replaced not long ago. I had a large tune up when I bought the car back in August
Personally I just want to chop off the cat but that's just me..

Don't you will hate yourself after 5 minutes of driving.
It wont only be as annoying everyone including yourself but it will feel even slower. I know when the cat on my 6 got clogged and cut it off before i replaced it. Felt like a moron ricer with loud ass exhaust

if you got that code for the cat and the rear O2 sensor is working properly i would say its time for a new cat. most of your symtoms are those normally associated with a clogged cat

looks like you got a legit reason to put those headers on.

It almost sounds like you have an electrical issue with cyl 1 either the injector harness or spark plug wires or possibly a big vacuum leak on that cylinder that is cause it to go so lean it misfires. I don't know the V6 engine setup well enough, but is there any vacuum or AIR line that goes to that cylinder? Does part of the EVAP go to that port, it might be pulling EVAP constantly and if a hose is cracked it could be a constant leak. Or could the intake gasket have gone bad around that port allowing air to leak in and leaning it out? It could be the leaning out causes so many misfires that it goes into limp mode and shuts down or stalls out.

No cat would kill my performance?
@Jeff
Why would I have a legit reason for my headers now?

Cause you can pop those on, and a high flow cat. If it fixes your problem, awesome, if not, well now you got your exhaust on, and it eliminates one possible problem, either way you'll win.

I had no cat on my 98 V6 firebird and it made 370 rwhp and 430rwtq on a 125 shot and 225rwhp and 225 rwtq all motor!! I would say it doesnt effect the performance. Mon my stock motor with bolt ons and a 125 shot I made 315rwhp and 410 rwtq.. That was with Headers, 3 inch exhaust, lid, and msd coil packs..

Haven't driven it around really.. except for the occasional few mile run in the suburbs. The smell of gasoline seems to be heavier now and there's some "Ssssssssss" noise coming from the rear of the car, I can hear it behind the right rear wheel like a hissing noise but not quite. Could be a louder than normal fuel pump?
I've also done some WOT runs in this thing through two gears.. still showing normal pressures all around.

I suggest not driving it until it's looked at, especially if you're smelling fuel. The fuel could be sitting in the cat, and can be a potential explosion danger, it could be sitting in the cylinders, which can wash the oil away, and damage internal stuff ( that's what happened to that Mustang engine I rebuilt last year).

On the lt1 cars, the charcoal canister is in the driver wheel well. I know most of the ls1 cars have it on top of the tank but I think 98s still had it in the well? Could be the same setup on this car and that is what he is hearing/smelling.

Yup, its under that pain in the ass plastic flap. I had that problem with my car, for a few days I would smell fuel, but only after filling up. The car threw up a GM code, and I replace the vent valve, but didn't fix the code. Turned out the crappy rubber hoses that connect it to the front of the vehicle. replace two 2 inch pieces, and fixed that problem.

Alright.. my course of action. New cat. That's my first step, it's definitely rattling alot.
It's a pain in the ass to start the car sometimes -won't even try to start on some key turns
Ignition or fuel pump are my focuses now

You may want to check the EVAP lines going to the charcoal cannister behind the driver's rear wheel first(if that's where it's located). They can get rock hard over time and crack. The hissing noise might be a big vacuum leak from a cracked or disconnected hose. That would cause it to lean out pretty bad and give you the gas smell from the charcoal cannister.

New cat is getting installed today, took it to a mechanic and that's what they said the best bet was.

Costs so far this past month for the Camaro = 150$ Towing after breaking down, 50$ Parking Ticket (...I WASNT EVEN 5 yards NEAR asphalt) 100$ Fuel Filter/Labor, 300$ Cat/Labor
Grand total of 600$ for not even driving the damn thing =_=
