Hi Folks,

The CEL light came on with Code 11 (air injection) and I discovered that one of the vacuum lines was disconnected. Checked for other vacuum leaks and no other leaks found. Reset Code and car started right up with no problem.

When I step on the gas, I can feel a slight hesitation from idle. When pass 1K the hesitation goes away. The hesitation is more pronounced as the car gets to full operating temperature from accelerating from 1K. At one point, the car died at idle when stopped. Car started and it felt like fuel deprivation at lower RPMs but okay at higher RPM when accelerating; managed to get home.

I will check the plugs, rotor, cap and ovp later after the car cools down. Is there a correlation with Code 11 and what I'm experiencing right now? I'm inquiring so I can be more efficient with my troubleshooting. Thanks in advance.
