91 240 HB
Like the title says, when I'm accelerating with consistent throttle, the power delivery is not smooth. I know that HP and torque curves are not straight lines but it feels abnormal. It'll accelerate good up to 2000 rpm, then power disappears for a ~300rpm, then it reappears. Any ideas? Vacuum leaks? Timing belt? Thanks in advance for the help.
