Start with the easy ones, add a fuel additive: techron is good. And change your gas station. See how it does.
I’ve used Techron and Lucas additives. Sam’s Club 87 and 93 octane, also Brookshire’s gas.

I might just change the TB. It has 84k on it and an unknown maintenance history.

I'm wondering whether it could be caused by the intake manifold being gunked up with oil from the PCV system. I have had my catch can on for 25,000 miles and must have dumped half a quart of oil out of it over the years. Do you have a catch can?
