After the O2 sensor was replaced, I did spark plugs and fuel filter just in case, all were fine as the had been done less than 8k miles ago, no loss. Then decided to check my valve lash (hadn't adjusted since new cam was put in) and of course two of the eight that needed changing initially required another adjustment (been collecting from JY for years now). That helped a lot of the shaking, but it's still not where I want it.

When I disconnect MAF, O2 sensor single-wire reads 0.95, reconnect and it wobbles all over the place usually 0.3 to 0.7 VDC, is this where I want it? Should I adjust fuel screw, or is this normal?
