As a side note, and a strange turn of events, I just went and started my car up and took it for a drive and it seemed to run almost perfectly. Idle was good (high) and it started up fine even after repeated shutting off/starting. Could my problems be related to the cold weather up here or what? It's just a strange coincidence that today it hit 60 degrees and the car ran a lot better (still no vtec engagement though...) whereas the average temp has been like 35 and it ran like crap.
