Ok, pretty sure I found the problem.. It's a bit embarrassing but if someone out there can learn from this it's worth the post. The air filter was completely plugged. I always clean it (K&N filter) at every oil change but forgot to do it this last time. I think my girlfriend was distracting me.. Anyways, I have the evo 1 air box lid & that lets a lot more air & dust into the filter. Along with a pretty oily filter it starved the engine of air I suppose. I never did get a temp light. So live & learn from my mistake!
