Help! Lost tachometer, water t. gauge, alternator wont charg

[Saber]

Thanks. After alot of measuring, thinking, looking at schematics and remeasuring, I finally found the culprit. It was just a fuse, ONE F*$KING FUSE! It looked fine, but when I measured it, it was open (burnt). I think it was the combination meter fuse. For some reason the car wouldn't charge without it.

Fixed it. Been driving the car since then. All was fine until last weekend, the battery came loose, fell infront of the engine, shorted to ground and literally cooked itself. Car died obviously and 1/4 of my engine bay was covered in battery acid. FUN FUN FUN!

Cleaned it up the best I could, swapped the battery and the car fired up like nothing ever happened. But now when I fire it up and the engine is cold, the car just stutters and chokes when under part throttle. Runs jittery when idle, bogges down/chokes under part throttle, but flys under full throttle. It's like the throttle position sensor only works under full throttle when the engine is cold.
But when the engine warms up, it gets better and better. When fully warmed, I hardly notice any bogging/choking/stuttering.

Weird...
