i have a 99 dakota with 98xxx miles.Iam getting a IAC code.I replaced the IAC and still getting a check engine light on.Every morning I have to keep my foot on the gas to get it warmed up and after a while its fine.But sometimes idle bouces.And at times it will idle at 1000 rpm and then lower around 600 rpm.Cleaned the TB,checked all my IAC connections but still cant figure out what the issue is.I was told my Advanced that if it isnt a bad connection that its probably the computer.Was also told my someone that its the MAP sensor or the climate control sensor.Can someone give me any input maybe?Thanks.
