morning all, i had a cat back system fitted by powerflow last monday, i put £20 worth of fuel in on the way home from powerflow had about 1/4 of a tank of juice in the beast so it near enough filled the tank. i've done 130 miles and its back on 1/4 of a tank !!! so i you can roughly say that i only got 130 miles out of £20 !!!!! i normally get about 160-170, didnt think the exhaust would have made that much differance !!!
so its either the zorst, a petrol leak (havent noticed one, cant smell it) or i've burnt a valve seat or valve guide out !!! car still runnin fine, except i noticed a bit of blue smoke out the zorst when i started it up from cold the other day . . but i'd just washed it, maybe just water out the zorst ?? and i was sat at the traffic lights last night and the revs dropped to about 300-400rpm and then went back to 900, then droped again, it did this a couple of times and then went back to its normal idle, i claened the throttle body out with some carb cleaner when i got home, that has seemed to have cured the old sticking throttle at low revs, bucking bronko business !!
any suggestions where my fuel is going ?? :? !
