I recently got my ônewö æ95 Montero LS licensed and on the road. Recently, when accelerating to 60mph on the freeway, the engine has started to bump, lurch and hesitate. About every 2-3 seconds it will jar itself. Slowing down to around 55mph, the truck drives normally. The engine only acts like this at around 60+ mph. Any thoughts on what would cause the high-speed s-s-s-stutters?

Also, the center console clock no longer lights up and the compass/thermometer gauge blinks on start-up until I press the thermometer button. Then it works normally until the next time I start the engine.

I also noticed that the interior dome light does not work anymore, even when switched on manually.

The clock, compass/temp gauge and interior light worked normally until a week ago.

I would appreciate any troubleshooting insight, including performing an exorcism.
