SKIP ON 3

OK so last week I had po303 on my 97 previa supercharged and checked all wires and rotor cap assy. Come to a stop when I could not remove the #3 spark plug. It was seized to the head. I sprayed it with WD-40 and after a good hour or so I was able to remove it. The skip was only on that cylinder so once I was able to remove the plug I installed fresh ones and the skip was gone. She has 235K on the odo and looks like the rotor cap and wires where replaced at some point but the plugs since they where all kinda seized up they did not get replaced. She is running so so much better but still lots of work ahead.:greenvan:
