A recent development.
Generally runs well, no smoke per-se, but rather noisy.
Recently at much over half throttle, the engine is holding back badly. No missfires as such, just a general lack of power, and occasionally some smoke at the rear, but not always.
Its been a while since I changed the fuel filter ( say 30-35k miles )......engine is of unknown history, although I have put about 50k of reliable motoring onto it since I bought it used for my car.
I had previously tinkered a bit, and at WOT had been seeeing EGT's close to 700degC, these are now down to a little over 500degC at full throttle, so clearly there is a fuel supply problem of some sort.
What sort of sypmtoms would a failing pump give ??
