Hello folks, Last Monday, after driving on the highway for a 1/2 hr in cold weather, I had a sudden loss of power accompanied by the unmistakable smell of a rich running engine. I'd had the front and rear heater blowers going, and for lack of anything else to try I turned them off. The engine's power returned almost immediately. Things have been fine since, but I haven't had the occasion to run the heat full blast either. I've been wondering what happened and came up with a couple ideas: #1: I'd overcooled the engine somehow, throwing off the air/fuel mixture. #2: Since everything (wiring, blower motors, etc) is old, running the blowers caused a voltage drop across the whole electrical system. With all the FI sensors giving info to the ECU by resistance to a specific voltage, perhaps the voltage drop creates misinformation. Or even effects the ECU's functioning. No crisis, but anything that helps with understanding how these things work is good for me. Best, Matt Sutton 88 GL 4sp Brooklyn NY |
