Starter problems and engine stutters periodically

[Angles]

Hi,
My first post. A couple of months ago my jeep starting having starter issues, particularly after a short period of time being re-started i.e. after an hour. Turns over OK but takes a while to catch. Usually starts fine after being left overnight but now same thing happening all the time. Have had the battery checked and advised its OK

Also periodically engine stutters when going over 2k revs, feels like its starved of fuel, change gear, revs go down and its then OK, getting dangerous as when pulling away it stutters and starts to buck until I drop the revs. All help gratefully received

I'd pull the plugs and check/clean or replace them as a start. Then the fuel filter. Maybe it is clogged enough that higher flow needed at high RPM could be causing the issue. Try some seafoam as well to clean things out like your injectors.

Edit: You can find instructions on how to clean your cylinder banks using a vacuum line and seafoam to do more than just dumping it into the gas tank.
