Hi,
I'm working on a 1986 cabriolet with CIS engine. I recently replaced the injectors with new Bosch, injector holders, fuel filter, air filter and plugs and was hoping to adjust the fuel mixture since the adjustments was setup for the previous injectors (were shooting fuel like a water gun).
When I plugged in my Dwell/Duty cycle meter, I measured a very high and constant 86.5%... When I unplugged the single wire O2 sensor, the meter reported a nice 50.1%.
Would you say that it is an indication of a bad o2 sensor or is it because the mixture is set extremely lean and switches to an enriched mixture when I unplug the O2 sensor?
Currently, the engine has a solid idle but hesitations under load while driving..
Fairly new with this very interesting CIS system - learning as I go. I appreciate your help!
