Hello, my name is \*\*\*\*\* \*\*\*\*\* to Just Answer! I will be assisting you with your questions today. Give me one moment while I review this.

Okay, so we will need to attach a scan tool and read the data from fuel trims at at and at the RPM's it's acting up. This will identify if it is a fuel issue or not. Then we can scope out the ignition system next checking for intermittent misfires. Hi, I’m Ron and I’m here to help you with your problem. I’m very sorry that your having this issue and together, we will get this figured out. I will need your help too because I can’t see, touch, hear or smell anything that’s going on with your vehicle. We may also require some specialized testing tools in order to assist us in diagnosing the problems due to the complexity of today’s vehicles. Please be patient with my replies, I reply back in question order received. If I send you an attachment, I will tell you, BUT, you will NOT get it on a phone; you must be on a tablet or PC. Please let me know when you are satisfied with my answers too so we can close out your question. Thanks a lot for using JA, Ron

I dont have access to a tablet or pc but I do have the code reader for the car. Can we still do this?

We need a true scan tool for these tests. Most code readers only read codes. not sure if yours is different. You can look in your owners manual to see if it supports these tests. Thanks again, Ron

Honestly I was trying to do this without my husband finding out and I'm thinking that's not possible. I'm sorry Ron. Maybe I will try again later. Thank you for your help.

You're welcome, thank you too. Ron
