1. Per the shop manual fuel pressure should be 58 psi +/- 2, so that is your first issue. Fuel filter and or fuel pump itself.

2. change the spark plugs
3. Remove the injectors and inspect. If you see any rust replace them. You can always have injectors cleaned and calibrated for a reasonable price.

Highflowfuel.com for your pump. Lifetime warranty.

Get the kit with filter and regulator included.

You can get a cheaper pump of Amazon...but if the black plastic canister filter above the pump is plugged...you wasted your money.

Also absolutely take the time to spray some carb or brake cleaner around the intake boots where they attach to the head and listen for any rpm change. Douse it good 👍
