Exhaust Leak Fix = Lag?
I have fixed my exhuast leak (missing header bolt) and replaced my fuel filter this past weekend with my brother. I notice thatsometimes when I step on it it still lags. The rpms are going up but the car isn't moving along with the rpms, then all of a sudden it kicks in and the car takes off. I have checked the spark plugs they all look good and the cap and rotor are new. I plan to change out the ignition coilas well.
Could by Throttle body be to small for my upper intake (Mods in sig)? I think it's the stock TB.

fuel tank baffle is broken and pushing gas away from the pump as you nail it.
my guess is the car dies out for a second when you whip a corner hard?

RE: Exhaust Leak Fix = Lag?
the baffle cannot be replaced. its tach welded inside the tank, and unless you are Rubber Man, your not gettin in there. a new tank is around $100 and it takes about 2 hours to do, on ramps.
i just did mine, for this problem, and i could smell gas as well. i never found the source of the leak, but replacing the tank fixed both.
once you drop the tank you will see what i am talking about. directly around the fuel pump there should be a piece of sheet metal that encompasses the entire pump, constantly holding gas around the pump. when it breaks off, and your gas level is low enough, it chokes the motor out when you nail it, cuz the gas is swooshing around.
also if your fuel gauge isn't working, this is most likely caused by the baffle actually smacking and breaking the sending unit, because it's just floppin around in there.

This explains my problem to a "T". My fuel gauge doesn't work unless my fuel is low and the gas light comes on. My brother said I would need a new tank when he was under there. Any recommendations on a tank to get?
Thanks for all your help.

a standard OE replacement tank from autozone will do just fine, thats what i used.
you'll notice a ring around your filler neck, that bolts to the tank edge, when you crawl under there. the new tank won't have the provisions to bolt this ring onto it, so you might want to remove it while your under there. it makes a little noise when you leave it hanging loose.
