I have a 1995 Montero SR 3.5L, 87000 Km (54000 miles). Since 8 months ago I have a ignition problem, when the car is getting hot the engine lose power and begins to stall because 1 of the 3 coils doesn't receive signal from the power transistor and the 2 cylinders attached to it doesn’t work. I have changed 3 times the power transistor but after 4000 km (2500 miles) approximately it fails again. I changed a new set of wires, spark plugs, even the coil that doesn't receive signal but the power transistor still fails after a while. The last time I took the car to the official technical service but they just changed the power transistor and told me that everything is ok. I don't know what else to do. If someone has an idea what the problem could be, please tell me.

 

Change the coil.

 

smell your ecm (fishy smell) sounds like the caps are leaking you can open the ecm and check (black tar) for leaks after time it will destroy the printed circut board
