I have an 03 STR and started to get misfires in two cylinders. I have pulled the plugs and there is oil on both the plugs and coil packs. Have both coil packs failed together or are they just shorting due to the oil? What might be causing oil to show up there?

Spark plug o-rings failed which is common. Sometimes cleaning up the coils will make them work again. If not you will need to buy new ones.

Answered in your other thread on the same issue. Mods please merge them!!

I have cleaned the coil packs and plugs as well as removed the excess oil from the plug well and narrowed down to one bad coil pack. Where is the best place to order? Aftermarket or OE?

Thanks

Spark plug coils for the STR are about $40-50 at the dealer. Might be the best bet.
