    Cold Drive in My GM

    Ok i need some thought and ideas. My GM starts fine in the winter but if i start it and need to leave right away without letting the car warm up, when going up a hill the car would chuggle chuggle and then stall. then it's a bitch to start again because everytime you start it up again and let your foot off the gas it will stall. I am thinking this is because the car not warmed up enough right. seems to be fine when it's warmed up. Also how long should i let the car idle in cold before kicking it down. I don't want to suck up all my gas.

      A warm car is a happy car. If it runs fine warm then let it just warm up.

        My moms 85 olds does the same thing, should kick off of high idle on its own, although I know this doesn't always happen. Just get to know how long it takes to warms up.

          well it doesn't kick down right away. you have to wait 1:35 sec before you can kick it down.

            Sometimes my '85 chugs away for a couple seconds or until I press the gas after putting it into drive with no warm up.

                    my auto mechanic instructor said there is no choke on this car because it's fuel injected.

                      Its not exactly a choke, its a high idle system thats the same as what a carb uses though. It has the choke thermostat and high idle cam just like a 2bbl carb does. No choke plate on top like a carb tho.

                          right side of the CFI unit. Looks like a hockey puck with a single wire plug on it. Follow the linkage rods and you'll see the high idle cam on the throttle shaft directly below the choke thermostat. That linkage needs to move freely. There is also a screw in there to set the high idle speed. How its supposed to work, the cam drops into place when you pump the throttle with the engine cold. This holds the throttle open for higher idle. As it warms up, the choke thermostat pulls the cam up out of the way, and you run at normal idle speed. If the linkage is gummy, it will either not drop in, or not pull off. If it won't pull off, someone may have adjusted the screw to lower the idle without realizing that they were fixing the symptom and not the real problem. If it doesn't drop in, well thats self-explanatory.
