I bought my first Wrangler (TJ-1998-2.5 L- 71K miles) 3 months ago, I performed a tune up on it and running fine.
Like 5 weeks ago, problems started on cold start-up, but "mathematically" the engine started at the second try in all cases. Last sunday we drove long trip to the beach, coming back we loss power like every 25 minutes, when that happened we had to stop the car, turn it off wait like 1 minute, and started to continue the journey. This happened both on the highway (5th gear), and up a hill (3rd gear).
Until now thought I should change the fuel pressure regulator, but this last events makes me doubt.
Any thoughts? Thanks in advance.
