Does it have the updated wiring harness?
Also, the wiring from the Throttle Body, can be bad, e.g. shorting out with outher wiring.
The 1100 RPM idle, if the wiring (throttle body) is bad, it has the ability to take out certain inputs on the e-gas computer.
Only way to find out, is to cut the sheath open and see if there is anything left from the insulation (ECO Junk). YES, the throttle body had ECO JUNK too.
The symtoms you describe, do fit a bad throttle body wiring!
That crank sensor, I would replace it asap, along with any other blank wire(s)!
