Hello,

I am having some issues with my car. It has recently started acting up on me. It has codes 32 and 27.
Code 32 is power limited light lamp failure.
Code 27 is injector control circuit that doesn't respond to the control signal.
When the car starts to idle rough and burning rich is when it throws the engine light. After a few miles it goes away, and the car runs fine.
Any idea what could be causing this issue?

I have seen both the MAP sensor and the engine control unit cause this problem. It can also be a sticking fuel injector, I would start by removing all spark plugs and see if one looks different than the rest, if so, this will be the cylinder that is having a problem. If they look the same, I would replace the MAP sensor which is the engine controller. Check out the diagrams (below). Please let us know what happens.
