Blown Ecm Fuse

I have a 1992 toyota 4x4 with a 22re. When the motor gets bogged down it will blow the ecm fuse. I have looked, but cant find a short anywhere. I was hoping that someone might have some ideas on where to look.

I'd suggest looking at the ignition coil with an ohmmeter and testing it to make sure it falls within specs.

Check you oxygen sensor wiring thoroughly. The O2 wires like to short out on the exhaust manifold and blow the EFI fuse.
