Default what to do about horrible gas mileage?
so recently the z has been getting really horrible gas mileage like barely 200 miles out of a tank. i seafoamed it about a week ago. think maybe the plugs fouled? should i try some new tr55s and new o2s? ill probably do a fuel filter too. any other recommendations?

why you worried about mileage then?
3.73's and 3600 stall will pretty much kill it

my car "WAS" my DD... since the new MPG's suck, and the prices are so high, i've since decided to park it, and drive it on weekends to car shows and such... it's gonna be my "tinkering" toy now...

I have the V6 2000 Mustang now for my DD... Gets a little better mileage, and is completely stock, except for BBK Shorty headers... it's a great commuter.

So basically what I'm saying in all this rambling is, buy a cheap beater/DD car and park the camaro (not permanently of course)...

4k stall and 3.73s here and I would still get 250 easy out of a tank. That includes a full night of racing at irwindale and any other highway shenanigans I get into. I hate when people think a stall will ruin your MPG. Just because it will stall that high doesn't mean you have to. I accelerate just fine and it will shift at about 2200-2500 under normal acceleration. People need to learn how to drive normal and only use the lead foot when they need to
