Just out of curiosity, with codes showing a large scale vacuum leak at the EVAP system, and O2 sensors saying overly lean (like if you have a vacuum leak); why are you looking at the plugs instead of checking out the EVAP system?

Well, at this point in time when we sat down to figure out what we could do to make the car run better we figured we would change the spark plugs at the same time we also purchased a OBD II code reader to really see for ourselves what was going on??? The shops or dealer is too expensive right now so we are resorting to our old mechanic days working on our MOPARS LOL and see what we can do... I do have another question for you how can do you wash the motor off to wash away oil etc to start fresh to see any real oil leaks etc. kinda difficult under????

How did the old plugs look? Was there still signs of an electrode on the end?

Looks like there are multiple issues, Wanagofast just discovered oil in the spark plug tubes (he sent me a PM this morning), so that is one issue. Will tackle vacuum leak(s) next.

Yah, we started the car just to see how it ran just with that right side done and it already seems to be a happier car...Yah, we are going to replace the tubes later those tubes need to be ordered I assume, it didnt misfire presently. We sprayed WD-40 on the plug to keep any oil off of them and dried out the tube best we could.

OK so they have all electrodes (2) on each plug present. I tried to attach a pic of them how do you attach pic to this post?? The other wierd thing is that the plugs we took out totally look like factory plugs they say "made in france", BERU ultra, 14 FR-7LDU R6 they looked pretty good . We put in BOSCH platinums 4's.

Here is the pic of the spark plugs from the ride side of motor now doing the left side...

I have seen worse plugs, but now you know where you are on spark plug maintenance.

As JFP mentioned there seems to be major vacuum leaks on the evaporator system... How does the seal on your gas cap look?
