    Yea, it prob. is a Heat thing. The Motor, IC, everything in there is prob. Heat Soaked.

    I see you have upgraded your IC to an External, and you have an upgraded SC Wheel. Did you install upgraded Injectors as well? Just a thought, if you did, you might be Fouling them out from being Idle for so long. Then as you try to drive, it clears up and they are ok.

    Another thing you could try is opening the Engine Hatch for a little bit while you are Idling, let the Air circulate in there and let ALOT more of the Heat out than the Blower can.

    If all else fails, order up the lower Temp Thermostat.

    When I removed the resonators, apparently I didn't reconnect the exhaust hoses too well. As I was opening up, suddenly big power loss and rpms wouldn't go over 6k. Was certain I f-d up a supercharger. Opened up the hatch and saw that exhaust was leaking into bay and had suffocated the engines. Reconnected properly and smooth since.

    Any chance you have a little leak that is building up & suffocating? No doubt Duramaxx is right with the fresh air & thermostat ans. Anyone with an avitar model like that knows about heat!

    My first thought was an exhaust leak, too...

    Idling doesn't give you much circulation. If you have an exhaust leak it can cause exactly the symptoms you are describing. I'd start with that.

    fresh air ideas

    Some ideas: use kanaflex 620 to get your intake closer to the side vents (but it extends the length of intake), punch some holes for flow-rites, upgrade your vent fans, don't put in the black plastic "tray" that sits over the engine compartment under your hatch . . . heat will rise & the two hatch lids are far from air-tight. You could even keep those hatches open a little bit.

    You could see if you have any good Flat & Dry spots for the Flo-Rites ( http://www.4-tecperformance.com/inde...roducts_id=504 ) and let the Heat naturally rise and come out through them.
