Default major problems

when i have the engine sensor fuse plugged in under the hood the car idles good. but the air to fuel guage reads 20 to 1 and the transmission acts weird. but when i unplug it the car idles high and runs a little rich until i step on it, then the afr goes up to 14.8 to 1. but drives good otherwise. wat is goin on here? fuel pressure is at 43 and goes up at wot.

well its the fuse that is in the engine compartmant fuse box. i changed my maf to an old one and the afr looks good. but now my fuel pressure is around 30psi, so im starting to think the fpgauge is a piece. but i still have a weird surge feeling in the transmisison while coasting down to speed and it only happens when that fuse is plugged in.
