Engine Performance problem
1991 Infiniti G20 4 cyl Two Wheel Drive Automatic 160000 miles
The engine on my 91 G20 Infiniti with automatic transmission with 160.000 miles has been running rough and missing inconsistanly. I replaced the plugs, spark plug wires, distributor cap, rotor, fuel filter, and PCV valve. The plugs were worn but not fouled. I then turned the ECU to diagnostic mode with no response from the LED lights or the Check Engine light. This blew the 75a fusible link which cause most of the electrical components not to work. I replaced the fusible link. The car started and ran for a trip around the block before the engine stalled and would not start. There was also a strong smell of fuel from the exhaust with liquid coming from the exhaust. All 4 plugs were fouled. I put in the old plugs and the same thing happened, it ran for a trip around the block, stalled and would not start. The plugs were fouled again. I checked the coil and power transistor and both tested fine. Also the fuel pressure was good. Not sure which direction to go in next or how it should be checked.
have the same problem?
