Re: 2000 3.2TL runs fine cold, not hot

I got the same year and model car. What I suspect is happening is that the PCM fails to get off default mode after the engine warms up. When you first start the car cold, the computer goes into a default mode, meaning, that all inputs to the PCM have preset values. But once the engine reaches operating temperature, the computer module shifts from default to operating mode, meaning, that it starts to receive and respond to various inputs such temperature, vacuum, etc. But when this happens the Check Engine Light (CEL) should be on. Check your temperature sensor. You have two, one to the gauge and the other goes to the computer. Try that. By the way I have 127K miles on my Acura and I'm pretty well satisfied with it but then that's only me.
