Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
Before we get started though, 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 patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

I would test the fuel pressure and volume with a gauge to start with, then check the exhaust for possible blockage. Let me know your results. Fuel pressure needs to be 4-7 PSI and volume needs a pint in 30 seconds.

Thanks, Ron

You can also check trans fluid level and color. It's possible we can have a power distribution issue too with the torque converter.

Thanks again, and please don't forget to rate me and keep this link in case you still need me again later on.
