Have a 1998 XLT extenda cab 4x4 4litre.
The oil and temperature gauges are going wonkey, as in going past the high line then dropping back, then going past the high stops again. I cleaned the groung from battery to the starter and 2 more smaller ground cables from the battery to the front frame by the rad. Everything worked normally for a few days. Now back to the same problem. Do I need to have a grounding strap from the chassis to the truck body? I don't see one on the truck.
