Re: 90 rough idle during cold start
Mine started hard starting, rough idle. Like the choke doesnt know wth its doing. Coughs and will die when starting without giving it a little pedal cold or hot, then idles around 600rpm a little rough but steady (s/b closer to 800 correct). Mileage took a crap and it smells rich to me. Ill adjust the idle screw to get the rpm up a bit and see if that helps.
It seems like the choke/computer is getting bad data from something but no codes as of yet. If it keeps getting worse it will eventually toss a code?
