When I try to get my car moving, I need at least 1600 RPM for the car to not shake at straight road. When i try to go normal quet start (1200-1500rpm) before releasing the clutch, my car vibrates , like it's going to stall. Can you guys help me ?; also it gets worse when the car is heated after highway and traffic. When the car is cold it barely shows the problem.

Hello. Vehicle is sometimes losing power during accelerating. The revs fly up as if i had the clutch engaged, and then drop again. Happens usually around 2500rpm.
