It's most effective if you remove your injectors from your engine and soak them in injector cleaner. The coils can be checked with a digital ohmmeter. You can also replace the tiny basket filters inside of them, if you really wanted to.
I did it once, thinking my injectors had to be plugged up...but all 8 basket filters were very clean.. |

certainly, if they are gummed up, it is worth it to try before spending a fortune on new injectors

You can also clean & test your injectors with a little DIY kit. I built one just like this myself when I was having fuel injector trouble, and it works great with a 9V battery.
DIY Injector testing/cleaning Carb cleaner is more effective than fuel injector cleaner, but I am not sure I would want to soak my injectors in carb cleaner or not. |

It's worth a shot.
I've seen some amazing things happen with old cars when the right fluid additives are used. |

Seafoam is practically worthless as a fuel additive. It will clean your intake manifold if you suck it through a vacuum hose. That is about all it's good for.
On the other hand....dealerships use cleaners like BG44K. |

It may help a bit, BUT if you are going to attempt to use something like that, it's better to use a specialty product that has one specific proven use. I don't advocate "add a can" fixes, but in some cases, it really is worth a shot. I would certainly attempt to flush out my lifters before I bite the bullet and do a cylinder head rebuild. But on the other hand, why would someone risk using radiator stop leak on a leaky radiator, when it's so easy to just replace it.

The most effective fuel additives contain high percentages of polyether amine, or PEA. The good ones I know off hand are Redline SI-1, Gumout Regane, and Techron. The cheaper stuff is generally worthless.

Used sea foam in the 1999 saturn at 90,000 miles when the injectors were dirty used 2 cans over three tanks of gas problem gone car has 130,000 now .Put a can in the 2003 chevy truck in the spring and fall 220,000 miles
and have had no injector problems .Used there tranny cleaner at 150000 miles still running the same tranny with no problems .So I guess i`m saying before you spend big $$$ spend 8 bucks on it give it a try |

Seafoam is about the best you can get for an off the shelf injector cleaner, you can put it in gas, diesel, in your crank case oil( most people recommend leaving it in there for about 75-100 miles) the store i work at typically sells a can per day or more. There is another way to clean your intake/ injectors using a vacuum line and such but i dont have all the details on hand and have never done it. Oh and its good for using on small engines too. Using Seafoam through a vacuum line cleans out your intake manifold, not your fuel injectors. (most people use the vac hose at the master cylinder) As far as using it as a fuel additive, I've seen just as many reports of it not doing anything at all, as people claiming that it worked. I don't believe there is even any proven fuel additives it contains besides maybe alcohol. (which burns better than gasoline, but is not an effective cleaning agent) Using it in your oil is a bit silly, when there are so many better alternatives. Flushing your engine oil is dangerous and shouldn't be done unless it's absolutely necessary. But Seafoam is probably safe to use regardless, because it doesn't actually contain any solvents or anything.

Don't know how bad your problem is.
When I got my IROC it wouldn't idle long after start up. It would slowly drop rpm and then die. The guy I bought it off of said it needed to have the injectors pulled and professionally cleaned. I started running bottles of injector cleaner through it and after about 5 bottles (two in the first tank full of gas and one each in the next three it idled just fine. I'd pour a bottle of injector cleaner in the tank a couple times each year and its still running the same injectors almost 13 years later. Has 186,000 miles on it now. |

About TechRon: GM has known problem with the fuel sender getting dirty from sulphur in the fuel and failing. Nothing I have tried except TechRon will fix it, and I have tried just about everything. One bottle of TechRon and 20 miles later the fuel gauge is working again.

Pour in tank additives can work or at least help. Don't be too surprised if they don't, what you're trying to do is remove thousands of miles of crud by mixing in a solvent that's diluted down to somewhere around eighty to one by the gasoline and merely driving as you normally would. It's usually worth a few shots though because it's cheap compared to the next steps.

Seafoam, BG44K and Techron are all pour in's that take driving the vehicle and possibly a couple of tanks of gas depending on how dirty your injectors are. I would suggest finding a Wynn's or BG shop and have them use their in line cleaner. It's much more effective as it is introduced thru the fuel rail and then the engine is run strictly on the cleaner. Then you can follow up with a pour in that actually does a better job cleaning the intake and exhaust valves.

There's a handful of them that are okay as a preventative maintenance sorta thing. None of them will really fix mechanical problems.
Chevron Techron is the only one I'm aware of approved by a few OEMs, GM, Ford, BMW, Honda and Toyota I think as well. Mostly to deal with sulfur contamination to fuel senders, causing weird gauge readings and such. Seafoam ranks up there with the Obama administration in terms of scams and lies. I wish I would have thought of it myself, I'd have been retired like seventy times over. There's nothing in that can that will do what they say it will do, it's three ingredients that you can purchase and mix together yourself to make the same basic product if you were so inclined. At best it's a waste of money, at worst it's a good way to fuck up an engine and/or catalytic converters and O2 sensors (if so equipped). ETA - I saw a fairly eye opening demonstration first hand of what BG 44K is, I spoke well of it for a long time until I saw this demo. It ain't all it's cracked up to be. |

I've always found the kits that attach directly to the schrader valve on the fuel rail work best - FAR better than any of the in-tank products. You disable the fuel pump and run the engine on straight fuel injector cleaner until the can is empty. 3M and OTC both make the kits. There used to be a more affordable version but that company isn't around anymore.
