2.3L w/ P0171 code
I have had this truck for about 6 months now. When I first got it, it had the P0171 code and was running a bit loopy, popped the hood and sure enough the hose to the pvc valve was disconnected. That fixed that problem for a while.
Now the other day it came back. Got it pulled at a parts store again and it was P0171 (lean bank 1) again. Oddly enough it runs fine though, idle is a bit rough but not really all that bad. I don't have a tach so I can't see idle changes, only can feel them. I checked for vaccum (sp?) leaks and couldn't find any. From here I don't really know the logical steps to take to figuring it out. As far as I know of possible culprits are leaking exhaust, leaking intake, low fuel pressure and bad 02 sensor. This weekend I am going to clean the MAF out with carb cleaner and see if that helps at all. From here what steps would you guys take to figure it out?
Truck is a 97 2.3L Ranger with ~127k miles.
