heat soaked idle?

[4g63t]

Car idles grate with the idle clamp on V3 but after I drive the car more then twenty min and park it when I go to start it it won't idle at all it just dies untill I drive it for a while then it will idle grate again. Its like it gets heat soaked and dosent want to idle. It only does this when you go to start it after it has been siting sitting for a bit

I've seen some bad temperature sensors cause problems like this on other makes of cars. The switch reads cooler than it actually is so the computer adds more fuel for a warm up open loop cycle which can cause a rich condition and bad idle on a warm car. The computer ignores the other sensors until it goes into closed loop monitoring. Could be caused by a bad o2 sensor. Are you getting any trouble codes on your CEL? That would be where I would start.

p.S. Could also be leaking injectors. When you shut the car off the injectors leak into the intake and the gas pools. When you crank it it has to burn off the extra fuel in the intake.

Yeah, mine used to do that. I replaced the ignition wires, and topped off my radiator. It doesn't really do that anymore. I also die elec. greased the plugs for the ignition components as well as the temp sensor that helped. My first guess was the same as you its like the wires get heat soaked, and the resistance goes up until it gets cooler air moving under the hood.
