[QUOTE="Vinnie_B, post: 16769616, member: 201678"] OK. P0172 - System to Rich (Bank 1) The Adaptive Fuel Strategy continuously monitors the fuel delivery hardware. The test fails when the adaptive fuel tables reach a lean calibrated limit. [COLOR=rgb(184, 49, 47)]Verify SHRTFT 1 and 2 PID value is between -25% to +35% and a LONGFT 1 and 2 PID value between -35% to +35% **** Reading beyond these values indicate a failure.[/COLOR] If your SHRTFT and LONGFT fuel trim values are out of value range check the following until you find the problem. Any one of these could be the cause: [LIST] [*]Fuel system [*]Excessive fuel pressure. [*]Leaking/contaminated fuel injectors. [*]Leaking fuel pressure regulator. [*]Low fuel pressure or running out of fuel. [*]Vapor recovery system. [*]Induction system: [LIST] [*]Air leaks after the MAF. [*]Vacuum Leaks. [*]PCV system. [*]Improperly seated engine oil dipstick. [/LIST] [*]EGR system: [LIST] [*]Leaking gasket. [*]Stuck EGR valve. [*]Leaking diaphragm or EVR. [/LIST] [*]Engine: [LIST] [*]Oil overfill. [*]Cam timing. [*]Cylinder compression. [*]Exhaust leaks before or near the HO2Ss. [/LIST] [/LIST] I realize this is frustrating but hang in there, go thru one at at time. You got this [USER=37951]@5.0 Hatch[/USER] [/QUOTE]
