Is your car modded? Still under warranty? Try a battery reset, sometimes that helps electrical gremlins. Disconnect the battery and put the negative and positive cables together for about a minute. ( battery completely disconnected.) Try again. You can have the dealer figure this out. Will cost you 1 hr of labor time at most.
They never heard of that method? weird .. i'll ask them to do it anyway! (although i never heard of it as well)

UPDATE :
1id10t - i asked the dealer about the method again today, and they have never heard ot it. Nonetheless, i asked them to open the hood and i wanted to try it right away. Long story short, crossing the negative and positive with the battery disconnected WORKED. I no longer have a check engine after about 30mins of car idle (had an AC problem we were working on as well) and 20 miles driving!
I hope it doesn't come back! Anyways the other issue is im STILL getting NO LINK when i try to read the ecu. It used to give me '0 CODE' when i didnt have a check engine...
Any more ideas? im gona try to data log and see if that can read my ECU and report back!

no communication
there is testing for this. I believe there is a manual floating around here. I would check any and all connectors going into the pcm.then you'll check power and ground on the dlc to pcm.

ps low voltage from the battery can cause no comm.

I have had vehicles come into the shop with a check engine light on, and then i goto connect and it won't. I have had a few were the wires on the back side of the connector have broke. I have also ran into a problem with trying to pull codes on some mitsubishi's but never an evo, sometimes the ecu transfers data different then the code reader does. In my case i have to use a different software on my scan tool. As i recall i had a 99 GSX were i had to wiggle the connector to get it to work.

UPDATE:
check engine is back .. i'm really starting to think it's the PCM ..
man i have the worst luck! A check engine light that won't go away, and you try to read it and you get a 'no link'. There is NO thread on this forum that's related. Never happened to anyone before. Dealer has no idea. This really sucks!

i'll double check on it this time myself (dealer has checked and said they were fine) :/
What would cause the wires to melt? I'm wondering if i were to check this on my own, is it as easy as just looking under the OBD II port and looking for melted, loose or damaged wires?! Or am i taking this process too lightly?

UPDATE: PROBLEM SOLVED
Phenix@XtremeBoost - you were right man. Something in the flash was altered for sure. When i flashed back to my previous tune check engine light was gone straight away and i was able to read my ecu. I tried flashing to the tune that was causing the problem after and i got the check engine again and i wasnt able to read my ecu.
Thanks everyone for all help! It's just weird how the problem appeared 3 months after i flashed and not straight away. This is what threw me off the problem being the flash itself.
