Recently my 305 has been idling really speradicly on cold idles, jumping from 800 rpm to 300 rpm and stalling but only when the truck is in drive. If i put the truck in nuetral it will idle fine. Since i got the truck its always had a slight buck at idle in park, kinda like a cough out the pipes. Would this be symptoms of an IAC going bad or is it anything deeper than that?
