Okay, the first thing we need to do is scan the computer for codes and data to find out why we're in limp mode.

most parts stores will read codes for you for free.

The problem with a code reader is that it does not supply us with the data we need. Some parts stores will loan you this tool too, for a deposit.

Please understand that I don't know your skill level or tools you
have to assist us. Also understand that I can't see, smell, hear, or
touch the vehicle either, so your patience is appreciated. JA is a
great Q/A site, but it does not replace a repair shop. So please
don’t shoot the messenger if I have to deliver bad news:)
If you are satisfied with my answer, I would greatly appreciate a 5
star rating now and I will still assist you after you have rated me
too if another question pops up. I don’t get credit for helping you
until you rate me.
Thanks again, Ron

Our goal here is to assist you in the repair of your vehicle by
supplying you with well educated information. We may not always
have the exact fix you wanted to hear, but our job is to get you on
the right track, which we always do. We can’t hear, see, smell or
touch your vehicle from where we’re at, so your understanding of
that is greatly appreciated. There are no magical or miraculous
answers, but we do our best to guide you in the right direction.
Thanks, Ron
