I have 111,000 miles on my 5.9L and wanted to add an injector cleaning additive. any suggestions? Normally i would just run 91 fuel through it but i figured its 14 years old so ill get an additive

 

I recently used sea foam in my truck, seems to have done the job pretty well

 

Is that an additive to the fuel tank?

 

Yes it is, though ive also heard of using in the vacuum line.

Techron is good stuff, in the tank only. Sucking it in your brake hose and watching the smoke is fun, but that's about all your doing is burning the seafoam. If you want to clean intake manifold go get Mopar combustion cleaner from dealer. Seafoam is mostly isopropyl alcohol, naptha and some other oils.

 

cool thanks man. any news with your jiggle?
