Engine Performance problem
2002 Infiniti I35 6 cyl Front Wheel Drive Automatic 87000 miles
Emission test failed - P1456. Replaced gas cap, disconnected battery for 48 hrs. When started - engine dies unless I press the gas pedal to hold RPM for a second, then I can release the gas. CEL is off but starting problem continues. After a week CEL came on again. I have a basic procedure for testing EVAP system from " Mitchell" but can not locate a EVAP canister. Will appreciate help.
