Hi all. My wife's 2002 Caravan Sport/3.3L developed a miss under a load. I diagnosed #1 cylinder as the culprit, pulled the plug, and it was fouled with a sliver of something (carbon?). I cleaned it, put it back in, miss still there. Then I replaced all 6 plugs, miss still there. You don't notice it much (if at all) when holding a steady speed. When you're going uphill or when accelerating, it misses pretty good and the engine symbol flashes. When you return to steady speed, it quits. I want to suspect an injector issue but value anyone's experience with a problem like this.
What's the best way to clean injectors, just to see if it helps.
