I have a flooded spark plug after a compete tune-up.
I recently bought a ‘98 Wrangler, noticed it was running a little rough and so replaced the spark plugs, wires, and distributer cap. Noticed one of the plugs was flooded with fuel. 50 miles later, now the new plug in the same spot is flooded as well. No smoke, just a crappy start with the flooded plug. What could be causing the flood? 2.5l 4cyl engine.
