Carter Single BBS Issues

The Car Talk radio show recently answered a carb question, telling the guy to look at his choke pull-off. Of course, people with 2000+ EFI cars then started asking if their choke pull-off might be the reason for their problems. With EFI, the output is just the electronic fuel injector duty cycle. No more mechanical implementations like "choke" and "accelerator pump", but EFI does require more sensors. With the old stuff, you can see it operate and thus get a better understanding, which also helps in trouble-shooting EFI controls.
