are you running the standard ECU with this new ported engine of yours? might be an idea to get an aftermarket one if you havnt allready.

Either way, sounds like it's running lean to me.
Check the injector connectors, my car did the same thing exactly when mine broke.

Maybe it's the steering wheel - seat interface?

Just kidding check your timing and tps. change your plugs.

Sounds like a vacuum leak. If it was an injector, it would'nt idle very well, or at all. This would also explain your 2k+ idle. CJ
