Fuel Injector noise? Anything to fix this?
I know many cars just have loud injectors (like my corvette), that can sound like a lifter ticking. This is my first LS and I know the engines are so quiet... but are they injectors supposed to be real quiet too? I know toyotas' injectors tend to get a little noisy as they age...
Would a fuel system cleaner fix this? I know its not a big deal... its just alitttllleee annoying.
Thanks!

This is true SK...
Maybe I'm getting the injector tap confused with valves, but after using BG44k on 3 vehicles (LS400-55k, Wrangler-135k, F150-65k) the tapping noise was MUCH less on all of them especially the Wrangler. The difference BG44k made is unbelievable! I've used Seafoam in the past, but didn't get noticeable results.
Quick note: On the LS after a long road trip right during treatment, when I pulled on surface streets, the idle was running 100-200 RPM higher than normal. This corrected itself after about 100 miles. I suppose the computer needed a chance to recalibrate after clearing those clogged injectors!
Bottom line, I get 1-2 MPG better, smoother idle and better throttle response.

It may have also cleaned your throttle body ,raising the rpm's.
I have used many cleaners and they only will stop valve clatter which i rarely have but an oil change always stops that but the injector tick keeps going and going.

I think they artificially raised the idle to satisfy me when all along it probably only needed a fuel injection service.
BG44k is only sold thru dealers (or ebay)...no retail. It's the stuff they use when they sell you a $125.00 fuel injection service.
