Engine Light Code *Update*

well before the G2G yesterday misterjohnson read (and cleared) my check engine light code and i got code # PO171 my chiltons book say PO171=System Adaptive fuel too lean (bank 1). now i drove all day yesterday with no problems and then after about 60 miles of driving today the light came back on. and the car is stalling out at idel or having a rough idel. to me a lean mixture makes sence with this problem but what does the description mean and where do i go next.

I'm feeling any number of problems....

so lets see:
fuel filter (have you changed it ever? it might be restricting fuel flow)
fuel pump (are you a part of the recall?)
clogged fuel injectors

obviously you're getting spark and air but for some reason there's not enough fuel and the ECU can't compensate so its gotta be somewhere in the fuel system.

im sorry to hear that its happening to you as a problem like this is a bitch to fix and can cause engine damage... so let me know what you figure out and if you need anymore help just pm me or shoot me an email... with school and stuff im not on FF much anymore... my schedule is WAY too busy for that.

good luck

well i called my local ford dealer and he said without runing more test there was no way to tell from that code, but it could be just the O2 censor or the MAF censor because of the SRI i have. has anyone elese every got a code from a SRI install? i think im going to do the O2 censor and reset the computer and go from there, advice from anyone would be helpful thanks guys.
