What have I done?!?!
Well I sea foamed my truck, it didn't smoke, but now runs like ****!! It will idle for about 30 sec and then starts idling ruff?? And then it might straighten back out for another 30 sec and then do it again or die, WTH is wrong?!?! It's a 04 5.4

Where did you put the seafoam in at? I always use the brake booster vac and have never had an issue. I have heard about some people fouling the spark plugs out and damaging an O2 sensor once in a while. I have been using seafoam for at least 10-12 years and have never had a prob. You could have fouled a plug.

Went thru the brake booster vac. I've always done it on all my vehicles and ne'er had these results? Never seen one not smoke and run rough WAAAY after it all should be out of the intake. If I fouled somthin wouldn't it run rough consistent?? Or wouldn't I be gettin a code??
