Just a guess, but could it just need a good cleaning of the throttle body? Seems like your problem is just happening on cold idle. If your idle air passage is clogging up or your throttle blade is gummed up a little it could affect cold idle quality. This is just a guess, though, but it wouldn't hurt to clean up your throttle body a little anyways.thanks for the help! seems like the clutch is fine..just finished replacing the exhause system. The other thing i notice is when i wake up to go to work, i start the car and it starts to idle...seems like the engines gonna die on me? it only happens when the cars been sittin for a while overnight. If the cars been sittin couple hours or so its normal...anybody know what that can be?
