p0174 system too lean bank 2 + flashing engine light
I recently got the P0174 code and the engine light also flashes some of the
time (misfire?). I have a Ford Taurus 1998.
The car runs fine except when I go up a hill it lacks power and cannot go
past 70-80Km and if I give it more gas it does not increase in speed but
instead goes into high RPM (around 4000). Maybe downshifts? Car runs fine
on flat ground. I also have higher fuel burn then usual but haven't noticed
any fuel leak. I do smell a bit of gas from the engine when it's running, but
it's an old car so maybe it's normal?
So far I have cleaned the MAF, changed the gas filter, changed the spark
plugs, put fuel injector cleaner and replaced a couple vacuum hoses that
were getting old. The car now idles better then it used to but the engine light
and lack of power going up a hill hasn't gone away.
