Well it finally happened. Check engine light came on.
Checked for DTC
's. Got a PO171 "system too lean bank #1" and PO174 "system too lean bank #2"
The PO171 also had additional information reading:
Fuel Sys 1 CL
Fuel Sys 2 CL-Fault
Calc Load% 30.20 ECT
STFT B1% -0.78
I'm old school when it comes to this stuff.....any of you younger folk help me out?
What are the common causes of these two trouble codes?
Where should I start?
Engine seems to run fine.
I cleared the codes last nite (too see what would happened) It ran all day today off and on in city driviing for about 25 miles before the lite came back on.
Any of you electronic gurus out there?
