Sea foam guestion.

[Burro]

Hey Lads I know alot of ya'll love an use sea foam in your machines, so I bring this question to you. I felt like one of my fuel injectors on my 93 Toyota truck was sticking so I ran it on a really rich diet of sea foam. Still hesitates but less than before. I haven't ran it all out yet, so still on a way rich sea foam diet. I got the emissions inspection done today and she failed with five times the Co2 than allowed 220 pass 1010 result fail! Do ya'll agree with the mechanic that running all of it out will maybe solve my problem? I know not a CB question but I decided to go this route from what I've learned from this site, so I thought I'd ask all of ya. Thanks for the info (fingers crossed running it out will work).

I don't know, but I wonder if the sticking injector would make it that high.

She had the sticking injector last year as well. I only put two thousand miles on it this year so not a priority too fix it. thought I would give mechanic in a can a shot.

SeaFoam is good, even great, but it is not perfect.  The emissions test is not fair, with SeaFoam in the gas:  the SeaFoam, itself, will alter the emissions gasses, as SeaFoam is mostly white oil, plus some other chemicals which your engine system is not designed to burn normally, so it will throw off the oxygen levels of the intake fumes, as well as the exhaust gasses.  Run the tankful of SeaFoam'ed gasoline out, then see how it is.  If the injector is plugged, you many need to replace it.

You stated you only put 2,000 miles on your vehicle.  This suggests that it sits for long periods of time.  I would suggest treating the gas with SeaFoam if it won't be driven for a while, to preserve the gas (up to one year).  This is contrary to what I said previously, about running the SeaFoam'ed gas out completely, but I think you understand my meaning.  Vehicles sitting, not being run, is hard on them.  The oxygen sensors can acquire a coating of different things, which will impair them, resulting in bad emissions.

Bottom line:  discuss with your mechanic whether he feels you should replace the injectors.  Ask if he can recommend a stronger fuel treatment -- there are stronger solvent additives available (Racor?), on the industrial strength level, where SeaFoam is more of a household strength additive.  Best of luck.  Cheers!
