I finaly got some time to check the voltage at the o2 sensor
disconneced it and took some readings
Voltage was at .2 vdc and some times lower under .1vdc
if I raced the engine nit went up once in a while to .8vdc
But not all the time especially after running for a while
Seems like when it got hot it stayed at low voltage

Injection check

I also checked voltage at termanal x11 terminal 2 & 3
getting .6 v at idle
But racing engine I was getting 12.5 vdc
What gives???
