I was getting a cylinder 1 misfire code in a Prius I purchased recently so I got new coil packs and spark plugs and the #2 3 and 4 came out easily and those are done but I can't get my socket to catch on the #1 and I was wondering if anyone has any suggestions. I got out an inspection mirror and I cant see down into the bottom like the other 3. I got out a wire and magnet and tried to clean out whatever was down there and it didn't help. Any suggestions would be appreciated.
Use your smartphone in video mode with light on to look down there... The most common cause of this problem is a rubber washer gets down in there some times.
Well I got it out with a copper pipe that i smashed into the plug to fit around it and when it came out it was caked in oil and debris once I got the new plugs and coil packs on its not misfiring and my average mileage on a regular trip is much better
