I'm gonna have to do this when I take my car out of storage in February.

 

BTW, if you do this on your lawn mower, be ready for some serious SMOKE!!! LMAO I will try to get a vid of it when I do my grandfathers next week.

 

I sent in a fuel filter replacement DIY but Remmy hasn't posted it...

 

I've done this. Totally worth it. I used the DIY here.

Just got to make sure not to use too much.

 

where do you pour it into at? and where is this diy all you guys are talkin about?

 

..DIY, do it yourself... yeah well heres the link, all the diy stuff is linked from the main page. https://www.hondacivicforum.com/m_142942/tm.htm

 

Well, I used Seafoam, 2 days later my CEL is on. I'll pull a code later. Got my fingers crossed! Twas it the Seafoam(yar!)? I won't jump to conclusions till I get the code.

 

would seafoam still work good if i just poured it all into my gas tank?

 

My local parts store has a fleet of S10's and they put 50K-100K miles a year on each, and the owner swears by seafoam! He say's its the best anti-carbon stuff on the market!

 

Ok I pulled the CEL code, #67 Catalyst system Efficiency Below Threshold malfunctioning or defective catalyst system. My guess is that the Seafoam burnedup/knocked loose a bunch of crud, which ended up in my catalytic converter. I followed the advice for high milage, by only using 1oz twice, and 1/3 can in the gas tank. Don't get me wrong, the engine runs a bit better, but beware other high mile(164k!and counting) folks. This may explain the puffs of smoke under my engine while using Seafoam(see above post).
