Toyota MR2 Message Board - View Single Post - 20V MK1 Engine Swap Engine stumbles, badly

I just finished my 20v BT swap, and the engine is stumbling badly, especially at 2k-4k rpm. It's lessened somewhat if the throttle is kept near closed. I threw some 94 octane gas in the car to offset the 87 that was in there, so it's probably something more than that. What do you think? Timing?
