Is there a better term for losing power until I came to a complete stop?
I haven’t had any hesitation starting since I got my car back. Maybe I was drawing more than the car was able to recharge while I waited for Mom to take me home.
I cannot imagine that slightly-corroded battery terminals would cause my car to come to a complete stop on the highway, but then work fine 5 hours later, but I cleaned them.
At first I thought that I was in limp mode, which would explain being limited to 1,500 RPM, but not being unable to move my car.
In the back of my mind I wonder if I have 2 problems or at least my car does, or among the problems my car has, there are 2 relevant to this discussion, but neither causes an error code?
This discussion is about limp mode without a CEL:
I doubt you have a bad ECM, that said if the CEL is on there is a code set. The only time I have heard of issues with the dash not working properly and trouble reading codes is a battery issue. The first thing to look at would be the cables to the battery, they need to be clean and tight. Then check the body ground and make sure it is clean and tight. Also, check the engine ground connection and the transmission ground connections. If you have a voltmeter check the resting voltage of the battery, it should be 12.7v on a fully charged battery. The other issue it could be is a bad temperature sensor, there are 2 . 1 sensor for the ECM and 1 for the gauge. There is 1 fan switch sensor on the thermostat housing.
Not only did he experience limp mode without a CEL, but the car had difficulty starting.
I don’t know about those sensors, but I should check the grounds. I found the diagram in the FSM, so I will check those.
I ran across this: “Insufficient oil pressure will throw the ecu into limp mode but no cel and no idiot light(until 7psi or under).” Ecu limp mode without CEL possible? - Honda-Tech - Honda Forum Discussion
How low would the oil pressure need to be for my car to come to a stop?
I will check the grounds and start working through this troubleshooting guide: The Basics | EricTheCarGuy
