Truck was running normally. After turning off at a gas station for a brief stop, upon restart the engine had a poor or irradic idle and same when put into gear. When throttle/ acceleraton was applied or attempted engine would hesitate and stumble at any rpm. I changed the inline fuel filter located under drivers seat. but no change, and the check engine light has been on & blinking since the trouble occurred. Also there is a terrible odor coming from the exhaust that smells like sulpher from a burnt match or like burnt gunpowder.The odor usually only occurs when engine is warm or hot. I have read some q's & A's from your forum & suspect this may have something to do with the o sensor (s) please give me some input as to your thoughts. thanx R.N.
