Intermittent stalling after oil cooler replacement
Hey all.....hoping to get pointed on the right direction. Recently had an oil cooler EGR cooler replaced. On my first big tow broke down on a major highway. Got it towed to the dealership and diagnosed as a blown out IPR screen. Replace the entire IPR and had no problems the entire trip. A few week later I am sensing the same problems again that i had before the major blowout. Randomly while driving down the highway the truck will stall for a half second or so and then kick back in and continue fine. Seems like the truck loses fuel for a second and then regains itself. And it's not always at speed either...sometimes just coming to a stop I can feel it. Now this has only happened three times in the past 10 days or so but seems like it needs to get addressed. These symptoms are similar to what I experienced before my major IPR blowout. After it was replaced I didn't have any of the stalling problems but its now happening again. Could I possibly have some gunk in the IPR again that's causing this intermittent problem? Or something else altogether? Thanks for the help!
