Why is my van backfire when accelerating and running rough, sputtering
It's running rough, sputtering , I push on gas it backfires loudly. It almost runs like its a stick shift waiting to shift gears
You probably have a bad spark plug wire that's leaking and arcing. The best way to verify this is the problem, is to while idling, spray the wires with water from a hose (light spray) or spray bottle. When you wet the wire that's having issues, you may see the actual sparks coming off the wire, or the van will start running really rough until the water evaporates. I believe, if that's the case then, replace all the spark plugs and wires at the same time as it will save you much aggravation & money.
