Hi there
I have a 1994 GT, it has about 96000KM, or about 60000Miles. I have developed an idle issue , it starts fine, as it warms the idle becomes rough. After i go for a drive, lets say 15mins, at a stop light, it starts to surge and throttle up like it wants to go. Sometimes when i go into reverse and back to drive the idle dives and shoots back up, once it stalled. Any ideas what it can be?
