CA Idle problem when cold.

Hey guys,

I need some help/info. It started happening after it was raining all day in Southern California. When the motor starts from cold around 14-19C the idle likes too dip from 900-600ish and is never steady until the motor is warm. When the motor it idles completely fine.

Thanks in advance.

I notice this too on my 94 FD right after the rain also I'm located in So Cal. I let it run for a little bit and when gets warm then it went to a normal idle. I wouldn't be too worried about it unless your car completes turns off while its in idle.

Yeah, it's a tad strange. My TPS is in specifications and I have changed out my IAC as well.. Any thoughts? I'm currently re-learning idle on the PFC. If not i'll just bump my idle a tad bit.
