Hello all -- here's my problem: The exhaust on my 245 smells bad, like when you first start up any car, except it smells bad from the beginning, and after the car has warmed up. Also, the fuel economy is terrible; I used to get 320 miles from a tank, now it's down to about 200. Smells worse after I've been "getting on it" a bit to keep up with Chicago traffic.
I suspect a (rich) fuel problem. The car has two new fuel pumps, and I just had the injectors overhauled (the ECU had thrown a "fuel injector" code and the generic "compensating for lean/rich mixture at idle" code).
Fuel pressure regulator? I removed the vacuum return line to the manifold and didn't see or smell any fuel. Other tests?
O2 sensor? The ECU didn't throw that code, but could it still be bad?
Cat?
Any other fuel injection sensors to test?
Car has only 146,000 miles on it and runs like a scalded puppy. No discernable black smoke or oil consumption, dipstick smells like oil, no white or blue smoke either. But when I'm sitting at a light for a minute or two, the stank gets pretty bad...I've had to turn off the engine and open the windows on some single-digit days in Chicago to avoid stinking myself out.
Thanks!
