Fuel injection cleaning

[Lurch]

I have a 2001 Ford F150 that sputters a bit at times. Thinking I would start with cleaning the injectors first. What is better fuel additive or take in for a cleaning?

SeaFoam

I hear talk about Sea Foam and BG 44 K all the time.

B&G 44K. Only if you're going to run the tank down till the low fuel light goes on, in 1 sitting. That stuff is strong and will start breaking down old fuel line if it sits around.

How many miles on it? If you're near 100K and haven't done the plugs do them. Fuel filter replaced, last time you clean the MAF sensor?

There's more than a FI cleaning that may be the issue

Try the above addatives. You generally have to pull the injectors to bench clean them, this does much better because you can visually check them also. At that point you need to ask is it better to have them replaced? Parts cost on the set looks like $150 and you need to do that exact labor to have them bench cleaned.

Some vehicles with common fuel rails can run a purge chemical though.

Thanks for the advice I will clean the MAF and add some seafoam. Fuel filter and plugs have been changed within the last couple of years.

Years it what i gauge some vehicles on, until i check mileage and realize it's been X thousand miles ago.

I recently had a misfire code on cylinder 4 on a hemi... I pulled injectors 4 and 6 to swap them, but also tapped them upside down while they were out- and some sediment (that would not likely dissolve with cleaner) came out of the injector on cylinder 4. No more misfire code (was causing enough of a flow issue at full throttle to throw off the mixture on that cylinder)

Point is, there is a pre-filter on injectors and stuff can get caught in that- they can be ultrasonic cleaned as well to dislodge stuff caught in that pre-filter.
off-car cleaning is more thorough than in-car cleaning...

This! And try to get it from a shop. It is a little stronger than the cans at Napa, or so I was told by the BG folks.

In some vehicles, injectors are cheap enough that if you are taking the time to remove, clean and reinstall injectors, it might be worth it to just put in new ones. Even more so if you were paying a shop to do the injector remove/clean/reinstall.

Also, be careful removing and reinstalling injectors... the injectors often have o-rings that get brittle over time. Reinstalling with the old brittle/cracked o-rings can result in a fuel leak.
