Anyone ever have a seafoam related problem? Ive done it a couple of times, however, the last time i did it i didnt get the car to operating temps, and during the seafoam run it started hesistating then i took it out for a spin and its missing like crazy and throwing the random/multiple cylinder misfire code. Anyone have any suggestions as to what happened?

 

Could be your O2s got fouled. That's a chance you take when using stuff like that.

 

would the o2s getting fouled cause the car to throw the random cylinder miss code and bog at all rpms?

o yea im also getting slight black smoke and the smell of unburnt fuel is very evident.

 

did you 'clear it out' after putting the seafoam into the car? Might just need to be hammered on a couple times.

 

yea it got cleared out...and yea i hammered on it thinking it might need some help burning fuel, but its missing like crazy and not burning much fuel.

That will happen with that stuff. It doesn 't burn very well and your car will run like total crap until you get it out. Mine would hardly start and had no power at all. It was hesitating, backfiring, stumbling etc...Don't worry, just burn that stuff out of there.

 

May have to change your plugs and O2 sensors cause that stuff fouls them up pretty bad. That's why it's recommended right before a full tune up. Good Luck.

 

yea im changing the plugs right now...up until the pass. side front i was only 2hr 25min in.

 

Your probly have a fouled up O2 sensor. Its possible the plugs would be fouled out too? However I would think that they would burn themselves clean if you ran it hard a few times ?

Either way, a bad o2 will make it bog and miss. When I had a bad o2, my car would sputter like crazy under any load, unless i went to full throttle ( Or close to it, where the computer over rides the o2 input )

If you floor it does it seem to go away ? If so then I would start with the 02's ... if the problem still exhists, then its probly the plugs.

 

nah it doesnt go away at WOT...although ive changed 7 out of 8 plugs(getting the last one tomorrow) and 3 of the plugs were fouled so hopefully it will run right.
