Yep, one problem down. If you watch the O2 sensors on the scanner the 1/1 should be making rapid changes from about .200 to .800 volts. If its staying on the low side its detectin a lean condotion. If you use a propane torch and let the intake suck up the propane with the torch wide open, you should see it go high after a couple of seconds. Shut the propane down and watch it, it should drop low after a couple of seconds, the begin to swith back and forth. If it doesnt its an indicator of a lazy O2 sensor. Also what does it show for ect temp? Som
