Slow to Accelerate
When I start my '84 944 in the morning heading out to work, its slow to accelerate when I first pull out of my parking spot. It normally starts very well for its age, no problems, but its just initially after I start the car its like the engine is just slow for a few seconds. I'll gas it up to 2000-2200 rpm and let off the clutch all the way but after 5 or so seconds it finally picks up to the speed it should be at at that rpm. Engine problem or something normal? Even I have problems waking up in the morning

I've owned several Bosch turbo cars that when cold hesitate when you first hit the gas after starting it. Only occurs if the car is started an immediately driven. I'm thinking there are a wide variety of causes.
I've had a wide range of solutions work for me, which makes me think this problem is created by a variety of different circumstances.
Here's what I've concluded:
-Oil in air intake system. This happened in my '87 9000 in which I rerouted the vac system, and also in my friend's 1995 Passat 2.0 n/a. In both cases I sprayed a hideous amount of carb cleaner into the intake, let it sit, and then started the car (it will take some time to start). This is only a temporary remedy, since there is a fault somewhere allowing a notable amount of oil to clog up the intake.
-Dirty spark plugs. Obvious.
-Loose spark plugs. I had a turbo car with a 10.1:1 C/R, and for some reason or another the spark plugs just loved to walk out every 2000 miles or so. This caused large amounts of smoke to pour out the back and a poor cold running condition. I dabbed a small amount of locktite on the plugs and they were fine since.
-As brett 944 said, any number of failing sensors can cause this. Also bad plug wires, a flaky mass air sensor, or leaking vac lines.
From what I've been able to deduce it always seems to be a minor problem with one of the major components of the intake/air metering or ignition system. Just my 2 cents....it sounds like you should be doing a bunch of checking up on various components about now anyways. Old cars, old car problems.
