Can someone tell me where the ground to the engine is mounted? I know on chevy's it is like a metal strap, Im not sure about toyota's I have a 1990 4runner 3.0 and I cannot seem to find it, and I think it may be a culprit for my runner acting as if it is going to stall but comes back on... It happens at various speeds and various RPM's....
TIA
