Car is a 20th, 1.8t 6-speed.
I noticed something the other day that is happening occasionally on acceleration. At partial throttle, usually pulling away from a light or stop sign, I get this weird hesitation. It only happens at partial throttle and usually only in first, sometimes in second. As the RPMs increase up to around 3k, it's as if I lose power for a second. You can feel the car stop accelerating for a second, then it begins to pull again.
If it's under heavy acceleration it never happens. It doesn't feel like the clutch slipping, more like the motor hesitating, but there's no noises or missing or anything like that. The RPMs don't jump up or anything. It's like for a second it's making no power, then it comes back.
Anyone experience anything like this. Anything I should check? Thanks for any help.
