Hi guys,

Hopefully someone may know something I don't. My 86 LXi takes forever to start when cold and idles very rough until the temp gauge starts to move. Once warm it starts/runs as normal. I had someone tell me it may be the IAC? (Idle Air Control? - not sure) switch, the black two pin one that's mounted on the rear of the throttle body. How do I check this? I have a multimeter but don't know what the readings should be. Thanks in advance for any help, this really has me frustrated....
