2016 ford fusion energi with 154k intermittent rough start when at idle
- Sometimes its starts and shuts off perfectly then sometimes it's so rough the whole car shakes. Was thinking it was dirty fuel fuel injectors. I used the a royal purple cleaner but no change. I change oil regularly. Haven't changed transmission fluid yet. It is a cvt but I figured it's at idle in park. So that wasnt on top of my list to do yet. I will say I'm very pleased with my hybrid and cvt transmission. The launch gear definitely launches for about 5 seconds then she's a slow mo. I use this car for work and its running 10 plus hours a day averaging 100 miles a day. Thank you for your time and God Bless
When was the last time you replace the PCV valve?
