I have a 2002 chevy blazer 4x4, 4.3l v6 engine 86k miles. Recently it has started to have transmission problems. While driving the tach will go up when stepping on the accelerator but it will take a few seconds for the vehicle to accelerate. Additionally while driving, if constant pressure isn't kept on the gas a slight " hiccup" with a drop then a surge on the tach which is noticeable as far as constant velocity goes. Is this the transmission or a fuel pump problem?
