Gilly or others,

At what duty cycle should I expect to hear the "ticking" on the purge valve? Vehicle is a G500 (motor is 113.962 almost identical to the 1999/2000 113.961)

I just conducted a "test". outside air temp about 30 degrees F, tank about 1/2 full. I put my stethascope on and it's as quiet as church on Friday night.

A few days ago I popped some codes (all P0). Yes, I filled the car while it was running. Would that "break" a purge valve? The codes were:

- 442 EVAP system leak detected (small leak)
- 455 EVAP system leak detected (large leak). Gee I wonder why
- 150 O2S 1 circuit malfuntion
- 130 O2S 1 Circuit malfuntion

Not sure how 150 and 130 are related to the fuel cap issue. Thoughts.

Had expected the CEL to clear per the Mitchell's manual 3 "trips". But it didn't so I disconnected the battery to clear the DTCs. I'll drive it to see what codes pop, if any.
