My issue happens only when I accelerate from a standstill. From 0MPH, I begin acceleration and once RPMs hit between 2000 and 4000, the RPMs might suddenly and aggressively drop and then recover. You can feel it in the car, it's almost like it's shifting gears. The problem is that this doesn't always happen, so I can't duplicate it for the dealership. It also happens more often when the engine is cold, but it will happen when it's warm as well.
If i'm already at cruising speed and then accelerate, the RPMs won't drop on me.
Do you think it could still be a speed sensor? How can I test if it's a faulty wheel speed sensor? Or even a faulty CVT speed sensor?
Welcome, Nice looking car. I'm trying to see whats in the background of your first pics cause I grew up in in central NH and if it's where I think it is I was in the next town over. good luck with the build man.
