EVAP Purge Valve & STFT
Aloha,
Anyone know the relationship between leaking EVAP purge valves & short term fuel trim. I have consistantly lean Long & short term trims (-6 to -7) & know if I pinch the purge vapor hose, the stft will return to normal parameters if the valve is leaking.
My question is...would a leaking purge valve cause the motor to run rich or lean ?.
