Sea Foam Treatment

[NotoriousB.E.N.]

I just finished the sea foam treatment through my brake booster hose. I did everyhting correctly and saw the glorious smoke show. Now after driving about 10 miles, my engine is idleing even rougher . anyone have any thoughts? Also my CEL is on for an EGR code (P0401 EGR flow insufficient), i replaced the DPFE about 6 months ago and it cleared up but now its back on. This hadn't caused a rough idle or acceleration before but I know it can't help much. Any thoughts would be very helpful...

Sometimes doing the treatment can foul your plugs. I'd suggest checking them to see.

I'll do that....if thats the case, i'm assuming they will need to be replaced......and i hate doing that

Yea it can be an unfortunate side effect....moral of the story, if you're planning on replacing the plugs, might as well plan to seafoam it right beforehand, so you won't foul good plugs.

i'll remember that next time, too bad they're platinum plugs...probably need to be replaced anyway, i got over 120k on the beast. well, there goes my weekend:thumbdwn::thumbdwn:

Yea, it sounds like you needed to replace them anyway, if they haven't been before. Good luck, I know the SOHC can be a bear to replace plugs on.

yea, i was gonna replace them when i did plug wires about a year ago, thats when i realized they were platinum plugs, so i left em in...oh well, i'll get some new ones and it should run like a champ
