When i drive the car and left off the gas a little and then give it a little gas the car bucks, between shifts after the clutch pedal is released the car bucks a little unless i press in the clutch. Now i have a Bran new Tremec 3550 with a new cluch, pressure plate, drive shaft etc... installed about a month ago. But the car did it before the new stuff went in. I went through the entire rear wiring harness and found no splices or shorts, and also the dash is ripped out and i still havent found anything. When it bucks though i hear this clicking sound sounds almost like a relay but its hard to drive and feel if there clicking. also i have a bran new fuel pump and filter. to me it feels like i'm dropping a cylinder because after it bucks the car wont rev any higher than 3K. Car runs fine and starts and also drives fine but it just bucks every once in a while. Just wondering if anyone has an idea or opinion on this.
