my nsx currently has 104k miles with the ctsc. the car has some hesitation when going full throttle. i changed my supercharger oil which helped some, but for some reason, i still had some sputtering when going full throttle. the car would have a delay when i just mash on the gas when at like 3k rpm. i have always seafoamed all my cars with no problems so i figure seafoaming the nsx would be fine.
i used one of the vacuum lines behind the throttle body on my autorotor (towards the front of the car). i disconnected the line, started up the car and let it warm up. i thought i was a bit weird that the nsx was idling below 1000 constantly even with the vacuum line disconnected, but i didnt mind it much because i thought to myself that the car will fluctuate in idle.
i filled a plastic cup about 2/3 full and used a clear plastic tubing about 18" with a id of 5/16" and started sipping the seafoam. at first, no smoke or anything changed with the way the car idled, it remained at the same rpm and remained constant, no fluctuations. when i got to halfway down the seafoam, i noticed the car changed its idle, the rpm went up to about 1500 and the car would bring it back down to normal. during this change in idle, the car started smoking, which is exactly what i wanted. it was almost like something "opened up" and let more air in, maybe the seafoam did exactly what is was supposed to and got rid of the carbon inside the engine somewhere.
the car continued to smoke while i fed the seafoam. i made sure no CEL appeared and none did. when i let the car "breathe" without feeding it seafoam, it would jump up and down in idle which is what i believe is normal. while i would constantly feed it seafoam, it would idle around 1000.
after the can, i let the car sit for a good hour. i connected the vacuum line back in, restarted the car, and the smoking would continue. as i rev the engine, more smoke would pour out. i drove it around and into the highway with smoke filling the air.
i dont think is just in my head, but my car feels like is breathing easier and more eager to got WOT than before. i no longer feel any hesitation when i smash on the gas like it did before. it idles smoother and gets from a stop more willingly than before.
for those who have used seafoam, share your experience. i have nothing but positive results i think.
heres a little video of how it looks like after the seafoam treatment and letting it sit for an hour. of course, after the video thats when the smoke party started when i let it rip on the highway. im thinking about doing it again, just to see if i will smoke or not. no smoke would mean nomore carbon buildup.
