Bucking Edge. I hope you welcome me to the party that seems to have been going for 5 years....
I have a 2019 Edge SE, 2.0 GTDI. It started with a check engine light but no performance issue although the bucking my have started less noticeably. I had the code checked and it was determined by a non-Ford mechanic that the EVAP purge valve was the problem. The code indicated that the valve might be the issue. Anyways, now the bucking is a problem and you can see it on the tachometer. This is new. It just bounces 100-200 rpms. I see people talking about the transmission, but why would rpms jump due to that? Could the bad evap valve have thrown off the system performance?
