I have a 79 Toyota with a 20r. I lost power one day wen driving and have tried everything to try and find the problem but don't know what else to do. I've put a new coil plugs wires cap and rotor and the igniter. But I try ed the GM swap cause the yota one is to expensive. I think it's a wiring issue. And I am pretty sur my ignition is good cause all the dash lights work. Please help I'm at my breaking point with this
