I just gave my car a sea foam treatment today It seems like it made the idle much smoother but to me it seems like it lost some power. Could of it cleaned so much carbon out it clogged the cat? Or maybe fouled a plug?

Maybe fouled the plugs.

More than likely wouldnt plug the cats.

Did u take it for a good long extended highway drive to burn it all out?

didnt take it for long drive really, just around town a little bit.

Also I poured it down the pcv valve while it was running but as I was doing so it stalled out and some of it went down the the pcv tube without the car running. Could that cause any problems?

Wouldnt think so. When I did mine I poured it right into the TB and it stalled a few times but it didnt hurt anything. I agree with fouled plugs.

If it was fouled plugs wouldnt the idle not be smooth?

poured some b-12 chemtoom (essentially sea-foam just cheaper) into the line going into the brake booster and it stalled rather quickly, didn't pour much of anything in the motor. is something wrong with my car? how are ya'll getting 1/3 or 1/2 the bottle in then stalling?

you gotta pour very slowly.
