1 Check Engine Light On problem

Failure Date: 03/03/2021

The vehicle is hard to start after I work a 10 shift. After it is started, it runs rough and tries to die. The only way to get it to stop running rough is to get it to highway speed for about 10 minutes. I have to rev the engine up with my foot on the brake just to get going. It has tripped the check engine light. I took it to auto zone to have them check the code. It says that it has something to do with the cannister purge valve. I have included the report from auto zone. I also did a search on the internet for 2018 Ford Focus recalls and it came back with the canister purge valve. Apparently my engine hasn't made it into the recall yet because nothing came up when I searched my VIN. I am afraid that I am going to try to cross a road and the engine dies right in front of oncoming traffic.

There are more than a few faulty purge valve and similar type valves on the Ford Focus possibly causing excessive vacuum in fuel vapor management system. The excessive vacuum may result in an engine stall while driving,. Without warning and without the ability to restart the vehicle, increasing the risk of a crash. And yet my year model and motor size did not make that list. But yet I have this problem on my 2018 Ford Focus se only @ 40,0000 miles . This could have been a huge safety issue w/ my young college student driving all hours of night on back roads due to her schedule. She had no warning no check engine light nothing. She was very lucky this did not stall on the highway. She could have been rear-end or who no what else. I believe this should me Ford manufacturing issue and that it should be added to safety recall list.
