Howdy from Tennessee, I'm Chris aka Moose. Who am I helping today? I'm glad you've come here to get help. I will do my best to get the answer you are looking for. I help many customers, so sometimes my replies are delayed, I will respond once available. I try to be online at 1-5 pm and 10 pm-5 am every day.
- Have you gone back to the place that diagnosed it but did not repair it correctly?
- Are you planning to diagnose and repair yourself, if so do you have a scan tool and smoke machine to find the leak?

Not sure if i feel comfortable taking it back to the same place. And I don’t know how to repair it myself.

Since you were not able to reply to the info request I sent. I cannot be as accurate and thorough as I would like in my answer. I hope what I can provide does help.
It may be best to take the vehicle back to the shop or to another to get tested again. The tools needed to find an EVAP leak are rarely owned by DIYers.
Thank you for seeking us for help, I hope I provided what was needed. Press reply if you need to follow up. If you liked my answer please let me know so I can mark your question complete. Moose
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
