so i put seafoam in my car about a week ago, via the oil pan, engine, and gas tank.
and right after i turned on my car the engine light went on..there was tons of white smoke meaning the seafoam did its thing..but the engine light's been on! However, my car has been running just fine. tomarrow im going in for some free warrenty work at the dealership, and they're replacing the oil, spark plugs and a few other things..could that take care of it? or would anyone have an idea of what it could be...?

 

They should scan the codes at the dealership when they do the warranty work. DO NOT mention that you used the seafoam. I have heard of Seafoam occasionally messing up an o2 sensor or an o2 sensor heater.

So how did you get your CEL to go off Falkore? Your thread simply said it caused a CEL...you never mentioned the solution that I can see.

 

It went off by itself.
