Any help guys my motronic fuse 87 keeps blowing when in D and give it a good amount of throttle. If I drive it slow it does not blow??? and when in R reverse it does not blow evan with a good amount of throttle??? Motronic fuse is responsible for the pass side under hood fuse panel?

So I take it no one knows what the motronic fuse does then? I would normally unplug the components and see if it still blows but I have no idea what it controls.

well problem found the o2 sensor wire was rubbing against the body frame with a good amount of throttle the engine would shift away from the fire wall, short the wire and cause the fuse to blow. Untill next time

Good troubleshooting. Electronic issues always seem like a bear to figure out.

Agreed especially when the car is 1500 miles away, (this is a friends car and I had to help him by phone) boo-yah
