SOURCE: my 2001 cadillac deville keeps giving me dtc code system to lean
Anytime I get a too lean DTC I first change the fuel filter if it hasn't been changed in awhile. You'd be surprised how many times this has helped.
Good Luck with it.
Bob
SOURCE: My Cadillac deville keeps popping codes p0171 and
You don't have MAF codes
Are you not aware you start with & diagnose
& resolved all code related issues first?
I don't see how you could change a MAF as you
won't know how to test it
PO-171 System too lean (Bank 1)
PO -174 System too lean (Bank 2)
That sounds like a vacuum leak that effects
both sides of motor
The front O2 Sensors get replaced at 100,000 miles
If that was done don't do them again unless they fail
80% of O2 Codes are vacuum leaks that lean out
the fuel mix. The Sensors are just reporting what they
see. It is up to a mechanic to find out why
When they report lean then the ecm adds fuel by
increasing injector pulse width thus bad gas mileage
I suggest buying a $50.00 code reader & study OBD2
Systems on the internet.

Usually answered in minutes!
also stalls often after started, sounds rough
p0401 - egr flow insufficient is also present
Have a 1999 Cad Seville with p0171 174
It was my sensors Upstream/Downstream. It ran really good after the 4day my check engine light came back on and now it's P1640 ( just my luck).
