So I have ben driving my rebuilt 86 engine since May and it ha been flawless Starts right up, idles smooth as silk. I had adjusted the TPS to 42 and the IAC setting to 18. This has stuck all year. This morning (in Connecticut) it was a bit cold and when I cranked the engine it would not stay running until I fed gas. When I got to where I was going I checked idle, etc. Idle in neutral was about 625 (usually about 850) and jumping all around. TPS was at 42 but IAC was at 170. Drove it home a couple of hours later and it still needed gas to start but when I got home the IAC was down to 80. Tonight it started right up and seems to idle a lot better but not as perfect as it used to but the IAC is still around 80.
Question? Does the IAC setting usually require adjustment when the temperature drops? I am reluctant to mess with the adjustment if it's just some kind of hiccup. What do you guys think?
Thanks
