Same case as my 4.4X5.

As advised by my mechanic, rough idling was most often due to dirty or failed MAF sensor or leak in the intake system.
The engine stoppage on stops whilke travelling, is due to dirty intake valve (space during idle position is clogged with dirt/gum).

-clean the MAF with carb cleaner and dry with hair dryer. If still failing, replace with new.
-clean the intake valve with wd40, and wipe dry.

-replace with new, or clean and reinstall with silicon sealant the gasket of intake valve (o shape) and the gasket of the front flange (located in between intake valve and intake manifold).

-check for cracks on the intake duct (located between MAF and intake valve), and make sure the two small hoses attached to it are tight fit.

-check tigh fit of the small hose attached to the side of the front flange of intake manifold.


try it, it worked with mine. best of luck.
