There is an an aprositficityy in that's, (ask Freedgr). I don't buy that foam stuff.....(or anything else) . I am fine at 270k and don't want to risk some film-flam messing something up. Just water applied right might remove carbon, but my plugs are "peachy" , no rush there.

So all your plugs are gapped at .035 and the color is even? . "]Best to post the actual code numbers here,"

Yea all plugs at .035. so far xj is running actually better after couple days since the seafoam. Picked up speed better and got somewhat better gas milage. Still went to check with a friend at a local shop and said everything was fine. I deleted the check engine light and hasnt gone back up but if it does and its the same problem then i know what it is..

So then seafoam isnt really recomeded??
