My Volvo has been giving me trouble when starting up after short periods of standing time. I don't have problems after the car has been sitting for quite a while (usually at least 1 hour): It starts up just fine, and I have no trouble shifting into gear. Everything's fine in the morning on my way to work; at lunch, if I go out; and at the end of the day on my way home.
When I do have problems, the car will start up, but the revolutions are at approximately 450-500, and the engine dies unless I pump the gas. When I take my foot off the gas to go to the brake and put the car in gear, it also dies. As long as I keep the gas going, everything's okay. I can usually "nudge" it into gear by keeping my left foot on the brake and giving it a little gas with my right. Once I get it into gear, no problem at all: It runs fine, and there are no other symptoms.
Anyone out there who can give us a clue as to what might be wrong? Sure would appreciate your help! Thanks in advance!
