Car moving forward and backward?

Hi,

When this happens, does the tachometer indicate a variation in engine speed? If you are stopped and place the transmission in neutral, does the idle speed change?

Let me know. Also, let me know if the check engine light has come on while the engine is running or anything you feel may help. I have felt this in vehicles and believe I recognize what you are experiencing. However, it could be an idle speed issue, the transmission not down shifting properly, and so on.

Take care,

Joe

Hello, the Tachometer is working properly and the idle speed also. No check engine light and nothing on the obd scanning log.

Hi,

At this point, the only thing I can think of is if the transmission isn't downshifting at the right time and the engine continues to try pulling the car with your foot off the accelerator. Or I guess something could be loose as far as a CV joint, but the vehicle is not old and has few miles, so that is unlikely.

Do me a favor. Pay attention to see if the transmission is placed in neutral when stopping if it still does the same thing.

Let me know.

Hi Joe, thank you. Do you think it is a normal engine braking behavior because of the CVT?

Hi,

Absolutely that can cause it. I just finished working on a Jeep with a CVT and they drive me crazy. LOL

Keep an eye on it and if it changes or the check engine light turns on, let me know.

Take care,

Joe
