Gday ya'll

Probably heresy, but I just add a dose of Techroline to my gas every year or so.

 

You can always get a fuel injector cleaning kit. There are several decent ones out there. No biggie.

 

I throw a can of SeaFoam in tank now and then.

 

Seafoam is great stuff, I've used it for years.

BEST advice I could give you on fuel injectors on a 99 would be to look into doing a MPFI injector swap... Maybe not right away, but if you ever have problems with the stock spider injector assembly that's in your 99 now that has the older poppet-style injectors, the MPFI spider on the 02+ 4.3 is a GREAT upgrade (fuel economy, power, smoother running, more reliable, etc) and it's a direct bolt in.
