perfect running, to completely dead in 2 minutes???
 

2000 s80 t-6. ran great with plenty of power. i decided to use seafoam (70% can in oil/%25 in gas tank, and last 5%.) almost as instantly i poured the seafoam into the intake the car started to run horrible, which is normal for adding seafoam.....drive around the block and it has lost alot of power, i smell burning odor and pull over to find both cats glowing red hot (clogged cats.) i get home and disconnect the down-pipe from the turbos, and drive it again....this time the car has less power, and will not go more than idle speed.

i bought a cheap code reader with gave the code random misfire....i put in new plugs with no difference, im going to assume its a coil? however the car will not run in drive more than 1.5k rmp (idle speed/aprox 5 mph) i know one or 2 coils the car will still run just rough/poor.

only way i can describe the engine is that the car sounds like a race car with a big cam but no power.

is there any way adding the seafoam could interfere with the coil packs?

soooo...many problems occurred within a 5 minute time period that literally went from perfect running to dead in the front yard :(

Was the car running fine before the Seafoam treatment? Where did you put it in the intake? May be you got some on the air flow meter. You should see a significant mount of white smoke if you did that and you should keep the revs high while add the Seafoam. I think its highly unlikely that you got multiple bad coils all of a sudden. Keep us posted.

i poured a small amount into each intake tube after all the sensors.what makes it even more odd is that there was NO white smoke at all. i have used seafoam on multiple other vehicles and always made my neighbors hate me for about an hour lol. i removed the coils one by one today and it seems i have 2 that are bad....i went ahead and replaced one of them (only had the $$ for one today) the car runs a little better but still NO power. i have sen and driven cars with one bad coil and they drive ok but this car has absoutely no power when its in drive and i press the accelerator.
