Arthur,

Yes, I disconnected the vacuum line from the regulator during the test. I didn't notice any fuel, but then I wasn't looking for any.

Deanyel,

I just reset the one code 19, not the others. I'll also try Arthur's suggestion of resetting the adaptation memory back to mean.

BTW, is there a simple method (eg disconnecting the battery for a minute) for resetting all of the codes?

Thanks -- Greg
