Hey everybody, for no reason at all my cars idle has dropped by like 400RPM. It might be the cold weather but even when it's warmed up it still idles too low. It usually idles at like 800-900 but now its at like 500-600 and sounds like it is going to die. This started one day when I pulled out one of the spark plugs to change them but than realized the rest were impossible to get to. Could this be the reason? (I don't think so) Could i just need a tune up because it has idled rough since I got it and i know i need one but let me know what you think. Oh yah I have 305 TBI so its not the carb.
Thanks

tune up is a good place to start, could be a bad plug wire

i have an 86 and it always idled low and would die and i tried everything except the distributer and that was it cuz i changed the cap but not the actaul distribter(mine fuel injected to)

Try checking the IAC (Idle Air Control) Sensor. I had to replace most of the sensors in my car when i got the Stealth Ram, but maybe the IAC is clogged or just simply needs replaced.
