Please help! My car is surging. U can be driving at a set speed even on cruise and then u watch the rpms bounce and rev out super high sometimes meanwhile speed stays the same. When the rpms finally drop the car surges or jumps forward. I have changed all the sensors and air filters! Any ideas

 

Auto trans or manual? If auto, check your fluid level. If manual, clutch is going bad. Sounds like it is coming out of gear.

 

Ya if the RPMs climb and you aren't going any faster thats it.
