I've heard some references to the PCV valve with misfire symptoms - certainly won't hurt.
Thanks for your reply, Rick
o-ring inthe connector itself. Make sure it hasn't slid back. Use electric cleaner and spray into it but lightly. Let them all dry and hook them back up.
Make sure you diconnect your battery before you start. so that it will rescan the code.
Good luck
The left side is tighter but you don't really need to remove anything. It is more a matter of loosening some things so you can move them a bit. The bracket on top of the strut tower can just be loosened so it will move out of the way. The dipstick tube will move aside slightly without taking it out. The cover on the left side will come out by pulling it forward and up. It looks more difficult than it is. The COPs are held in place with one screw and the electrical clip.
Compared to replacing the valve cover gaskets, removal of the COP covers is a piece of cake.
The first time I had a misfire, I had the dealer do a stress test and he found one bad coil. They participated in an After Warranty Adjustment on that one. Later I had another one go bad so I decided to change the remaining seven myself. I had already changed the plugs once so I knew what I was getting into but had no way to figure out which coil was actually the culprit. Eventually, they all seem to fail anyway.
An independent shop might not be too spendy. I don't know what the flat rate manual would say in terms of the time needed for labor but I doubt if it would be more that a couple of hours - just a guess.
When it all started it was a faint grinding noice i heard every 30 seconds when i was just idleing at a light or just rollin whithout applyin tha gas than a few thousand miles down tha rd. it did it more often and when i stop it progresses into a boiling sound?

And go here to find a repair shop in your area. Hopefully, there may be some reviews for a good one.

I want to do a full tune up. What all should I do/replace for a full tune up?
Thanks
Many folks just replace all the coils then later find out they performed a completely wasted repair. While you are in the valve galley, I recommend you check out the secondary timing chain tensioner as they are prone to early failure and are basically right there in front of you once you spend the time to get the valve covers off. This is on 3.9 V-8's. If you have a V-6, forget the above as they don't usually have this oil seepage and chain issue.
What could be the problem? where should I look to start? what can I do?
One incident like that would not be enough to cause coil failures. I would clean it up and make sure no new leaks are occurring and see if you continue to have problems.
The TAC errors listed indicate a problem with the throttle by wire system which may or may not be related to the oil and misfire problems.
