well, my car was sputtering really bad in 1st and 2nd gear when i start off, so I thought well I never have changed the plugs in my 325i so I guess I should...Good move on my part, they were the worst looking plugs I have ever seen! Some idiot put some AC Delco el cheapo plugs in there and I replaced them with some Bosch Platinum +2 spark plugs. After I got everything back together I took a test drive and all the sputtering was completely gone! I thought no wonder it was doing so bad look at those plugs! Better acceleration, way better gas mileage etc... Well today I drove it to the NOPI nationals which is like 125 miles from my house...All did perfect till we came back...As soon as we were leaving, after the car had sat a good 5 hours, it went back to its old self again and now is doing the exact same thing...On another board someone said I my have a bad coil and that they are like $130 each, does anyone know how I can test these or know anything else that could be wrong??? Thanks!

did you have oil on any of the spark plug wires when you pulled them out, or any oil in the hole were you reach down to remove your plugs? If so you may need a new valve cover gasket....(if none of this makes any sense, it is ok.....i am retarded....) ghead

We had just replaced the one on my friends car.....when we were putting on his new header, we also were putting in new plugs, and noticed oil everywhere, so we got a new valve cover gasket, cleaned out everything with brake cleaner......then put everything back....now it runs great.....dunno if this is helping any :P

looks to be some oil stain discoloration around the hex part of the plug. Was there any oil in the spark plug cavities? As mentioned above, this will most certainly cause major misfiring and eventually short out a coil pack. if the miss is there at idle, you can start disconnecting one coil pack at a time and sense for a change in idle quality. whichever coil you disconnect and there is no change, that could be your culprit. Sounds to me as if you do maybe have some oil that was in the plug holes. This would explain why after a long 125 mile drive, it developed the miss again. If there was any oil in the holes I'd replace the valve cover gaskets, clean the holes out really well, clean any oil out of the spark plug boots and then test drive it.

If i do test all of this and decide to replace the valve cover gasket is it a major task that I can do myself or will I need to take it somewhere? Thanks for the help!

YAY....im not a retard........i suggest using brake cleaner to clean it out if you have some.....just let the oil in there drain into the cylinder.....then once you got everything put back......it may take a couple tries to start it....and when it does start you will have a lot of blue exhaust smoke from the oil that drained into the cylinder...

in addition to the oil on the hex part, what do the electrodes look like? (hard to tell from the pics)

if it's black and sooty you are running rich, which can be caused by intake leaks. have any fault codes come up?
