Hey guys, I've been having a slight problem with my 99 cobra as of lately. It started about a week ago, where I would be driving regularly and the speed of my motor seems to linger while I'm upshifting gears. This only happens with the a/c or heater is on. Usually, when I'm driving I would accelerate and take about 2 full seconds so the speeds of the clutch and flywheel would match before I engage the clutch. But now, when I'm switching gears, the rev would stay at about 2500 rpm for a long time until I let go of the clutch pedal. Anyone know why this is and what i can do to fix this?
