Re: Engine died while going 40mph
Could have been crud, moisture or an improper ethanol or additive mix in the gasoline. If so, emptying or replacing the gas filter would be a first step. (No idea where it is on the WK2.) Did your engine light go on at all?
We had what a Jeep service manager speculated was a bad tank of gas that caused our Overland's engine light to go on and some brief roughness. The light was reset and all's been well since.
Stations are under enormous competitive pressure to shave every last penny off prices. So you can never tell what some gasoline is like, what with debris in station tanks and delivery trucks. One station near us that we had used was caught pouring water into its tanks, for example. It was shut down by authorities, but after I read about it I found our pickup's gas filter full of water although it hadn't yet impacted operation.
