I replaced all plugs and put new coil on cylinder 4 and got a misfire code again about week later on same cylinder. Not sure what it is? Any help would be helpful.Misfire is caused by several items and spark plugs are not the main problem. I had the same code several years ago.
As you face the engine number 1 will be on the left side and 4 will be on the right side. I believe that it is recommended to change all plugs anyway and coils as well.
Just finished a trip in the mountains in high temperatures with no problems at all. Came home and the next day removed all the bug debris from the front of the car and gave a very fast wash, no problems. Next morning drove out of the garage and vacuumed the car and removed all the junk generated...www.discoverysport.net
Well I ended up spending $2100 getting camshaft timing replaced. Now I have replaced plugs and coils and still having a misfire. At a loss at this point. Honestly about to get rid of it.If you looked at the link of my that you quoted you will find how mine was repaired
You never did tell us how you made out with your solenoid problem.
