We own a 91 YJ and the problems started about few weeks ago. It started to buckle up when I first got going but then it caught it self and was fine. Then it started to stall when I came to a stop but that also only last the first 10 minutes of the drive. I added some fuel cleaner and it seemed help.
Then a few days later it wouldn’t excel past 10 mph. It seemed like it wasn’t getting enough gas. Like it was choking for gas????
We have replaced the fuel pump and filter, spark plugs, O2 sensor, oil change and new muffler, exhaust and break lines. What else is left??
