1985/1 Porsche 944 N/A -- once the car is at optimal operating temperature, it accelerates/runs nearly perfect. During warm-up period or cold start, the car tends to have a hesitation during acceleration (typically @ 1.5k-2k RPMs). Once you push it past 2k-22k RPMs, it tends to be smooth acceleration on up. Again, after warm-up, this hesitations drastially reduces and nearly goes away entirely. Lower mileage well kept car. New plugs, wires, cap, rotor. Idles perfectly throughout. Does not appear to be running rich or lean (that I can tell). No smoke. Etc. Personally, I feel like it resembles a vacuum leak, however I can't seem to find one, nor does it do this after warm up.
