Hello, I've been having issues with my 94 3.0 pickup, it looses power, stalls, and wont start again, at seemingly random times. I've replaced fuel filter & air filter & recently put in a new cat. every time this happens I spray a can of seafoam into the air intake on the throttle body and she's good to go again. This has happened 4 times in the past 2 months, fortunately I was able to roll into parking spots every time. I checked the diagnostic sensor today and it read EGR system problem. Would a dirty EGR cause the engine to fully stall and not start again? or do I have multiple problems?
