hook it up to a scanner as odd as it seems the fc can be hooked up to a scanner even my s4 can which i have done before so you can read codes i used one of those snap on red bricks to scan it and it was fine

Re: car will not idle or rev past 3500rpm
did you ever check this? the wiring connector that plugs into the EOMP likes to go out on these. Had me irritated for the first few months I owned the car. everything read fine at the EOMP itself, and went through several ECUS trying to find the problem.
Eventually had to cut off the connector and crimped in my own connectors (if you do this be careful not to mix up where the wires go. I did the wires one at a time, then used the removed connector as reference to double check the connections.

Do you have a check engine light? if you do use the onboard diagnostics system to find out what circuit the problem is in...
Also checking the OMP is easy if you access it from below, and it DOES NOT require removal. Just have to reach over the undercover past the swaybar up to the connector. I will say it is easier with the undercover removed though.
Check it with a multimeter per the FSM.
If everything is good at the OMP (or MOP as the FSM calls it), follow the wiring up the front of the engine, there will be a connector right next to the TPS connector that connects the OMP wiring to the engine harness. verify everything is reading right right from that connector as well. I found my problem was the wiring that goes to the OMP. The lower connector was bad, breaking the circuit. It tiggered a check engine light and limp-home mode. In limp home mode you cannot apply much throttle or she'll lose power. I have two threads on that very topic.
I found after ordering a new ECU that mine was fine...
Do a search for your ecu code, there is a thread that goes through what ECU goes to what application.
