Answer: Aaron,
An idle of 1100 RPMs is too high. Normal idle for your engine once it gets to normal operating temperature should be about 750 PRMs. As I mentioned before, you throttle body and intake manifold should be cleaned. That also included replacing your PCV valve. You should also have your ECU inspected. If your ECU is malfunctioning, it may interpret that all your sensors are bad; even though they are fine. Check over the last list of items I sent you. You're bound to find your problem.
Good luck!
