hello all im new to the forum and i have a problem that nobody local can seem to identify. Any time i start my car (warm or cold) she runs awesome. within 1-5 miles the check engine light comes on. So i take it to the local parts store and their reader says "unable to connect." i take it to the local guy who does all the dyno tuning and he says he'd love to tune it but i have to fix the computer. His equipment read the live diagnostics but still no codes. i do smell that the car is running too rich and when the check engine light is off it will try not to idle occasionally. it almost acts like the IAC is bad. Any help would be great. :shrug:

To further clarify for the OP. The test port is in the engine bay and is mounted on the passenger side strut tower between the firewall and the strut tower. Further, these computers cannot be "flashed". I have my doubt's about the tuner as he doesn't seem aware of the system and it appears that he didn't check up on the type of system in your car.
