Hello I’m new to the page and just need help on my 1992 Camry Le V6. This one has the 3vz-fe OBD1 when I start her up (when the car is already driven for 30 minutes not cold starts) she starts like a cold start jumps RPM sometimes close to 3k rpm’s and warm up idles around 1200rpms. If anyone knows this problem thank you. Sorry I’m not every good at explaining.

 

Check the ETC sensor. This sensor tells the computer the temperature of the coolant.

The engine has an IAC valve that controls idle speed. Valve is mounted to the throttle body to bypass air around the throttle plate to control idle. Try cleaning the valve. The internet will have videos on this. Use a cleaner safe for plastics and O2 sensors.
