fuel milage

[stanzz]

Hello people,

I've been all over the net, looking for some answers.....mabey someone here can help.

Anyway, I don't drive an SX, but I do have a KD24DE (93 Altima), and it's been running rich. I get half the mileage I used to.

I've done the fuel filter, O2 & Engine Temp Sensors, plugs, filters, and even a computer analysis- even though I get no ECU light. I don't smell any gas (or other smells), the car runs perfect (no hesitation, stalls, or smoke).

Help?

Possibly leaky / stuck open injector?

Well, I don't see any wet spots on the injectors side, but there is on the exhaust manifold side......mabey a blown head gasket? does that make sense? would that cause bad mileage?
