looking to resolve some the issue my car (1990 xjs v12) is currently having passing emission. both times I have tested it it gets 4/2 for HC and 60/20 for CO. I did do some work on the car already listed below.
Made a new injector harness
replaced plugs/wires/distro/rotor/coils
and tested the injectors abit using a arduino pulsing them and measuring output volume.
I also just got a new seal kit for the injectors that I will install soon
the car runs great. The only thing I noticed were a slight injector tick which sounded pretty normal for the car and a slight inconsistency on the driver side exhaust compared to the other.
