im gonna go try the carb cleaner trick right now, forgot about that. Can someone tell me exactly where the choke and fast idle vac lines go. or is that too hard to explain. all of the diagrams dont show where the fast idle line goes and the choke is not even there. i just drove about 50 miles and its like i have a whole new truck. better response and plenty of power. just idle and start up are a little off. thanks for any advice.
