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.
