From my Foxwell, STFT ranges from -10.9 to 8.6%
LTFT 1.6-3.9 occasionally 7.8%
MAP 26-29 occasionally 42 KPA
MAF 2.85 to as high as 5-16 gs
Idle rpm 641-892
O2 440-535 V
Recent smoke test, new O2 Bosch, compression test, 130 to 144, MAF cleaned, new plugs, suspect original MAP at 215K although it was cleaned! Injectors were open but not misting like my 245?
No real long trips but getting about 20 mpg
Fuel pressure at 55 psi, appears to be high.
No misfire codes but will show p2177 a lean code off idle.
Timing belt reported to 10K per PO!
Xemodex TB was cleaned along with new gasket.
Thanks for any advice.
