Look, before you guys get all:
..hear me out!!
Ive failed inspection because of codes P0171 & p0174. Both banks are showing a lean condition. My first instinct was look for vaccum leaks (none found) change the upstream o2 sensors and/or check the fuel pressure.
Here is information that may apply to this:
1) changed the fuel pump/strainer/filter about four months (1500 miles) ago
2) cleaned MAF last month
3) exhaust has a few leaks but downstream from the rear o2 sensor
4) intermittent coolant leak from an unknown source on front of engine*
#4 is the reason I started a new thread.. Is it possible that the infamous intake gasket leak could throw the "lean banks" code(s)? This very repair was done about 8 years ago and I'm wondering what y'all think:
Should I pull the trigger and change the gaskets??
