I didn't know one of the criteria for it to go into lean burn mode was vehicle speed, I just figured it was based on throttle and engine load. Well I guess I may get to work a little faster today.

I have a compression gauge so I may get around to checking the compression this weekend as well, I have a Haynes manual for the car which shows for the SOHC D16Y5 engine "standard" compression (new) should be 184psi, minimum spec is 135psi.
