I am thinking of getting one and would like to hear anything you folks know on the subject.

 

if they do what i think they do when cleaning, you can do it yourself. i am thinking all they clean is the inside of the TB due to the blades sticking. if so, get some carb cleaner and spray some on a rag and clean it yourself. very easy to do.

also, it doesn't hurt to ask what all is cleaned by them.

 

Just got it done. Cost about $300.00. Didnt really notice a difference, except that my SES light came on after I got home.

Threw two codes, one was a emissions sensor and the other was bank 1 running rich.

My fuel mileage dropped to total trash. (from 430 miles per tank to 380). Took it in, turns out one of the vacume lines to the fuel pressure regulator came loose (hmmmm forgot to reconncet it maybe????)

Anyway they fixed it, but i'm still waiting to see if my mileage is back where it should be.

 

what all did they do? is it a lengthy process they go through and do stuff? all i can see that would need cleaning is the TB and maybe the injectors!

 

hey demon. what dealer did you take your truck to?

 

they sell intake cleaner at the auto parts store. all you have to do is pull the intake hose off the tb spray the crap out of it and wipe it clean with rag. for $300 i'd want them to pull the tb , intake and make them so i could eat off them. i'd also want the in'js pulled and run through a cleaning machine. sounds to me like another ridiculously inflated service by the dealer, i regard the dealer as a last resort as for parts or service. seems most auto makers design their vehicles with model specific parts that you can only get from them so they can screw you when it fails, rather then use a part that would work just as well and is readily available anywhere. sorry about the rant, i just friggin hate dealers. imo don't waste your money.

 

Supposedly they did pull the TB and Injectors.

It took them about 3 hours so I'd think they at least went a little in depth. I took it to Hudiburg Chevrolet.

 

If they did what I used to do as an induction service, then it's a pretty good service, and for $300.00 it better be. When I worked at the dealership(was a Toyota Master Diagnostic Technician, now got a bum back, shoulder, and elbow, oh well), we used to do a BG induction service. It invlolved a pressurized cylinder with a fogger nozzle that went into the throttle body(pull of the air intake hose and make sure there's no air leaks). Two different cans of BG chemicals gets forced through the fogger nozzle into the induction system and one can gets added to a full tank of gas. It smokes like heck when you do it and sometimes the check engine lt comes on due to the rich mixture and small percetage missfire that occurs during the process.

I've actually had cars fail NYS inspection for NOx and performed an induction service on them and they went through with flying colors. I've also checked a few out with a bore scope before and after the service and been pretty amazed at how much carbon acutally gets cleaned out when the service is done properly. I always cleaned the throttle body with BG throttle body cleaner as part of that service also.

With the carbon issues that I've heard to be a problem with the NBS trucks, a service like this should be a once a year maintenance. Basically the same principle as SeaFoam or GM top Engine Cleaner, Just a little more fancy and engineered.

 

well if they pull and clean the inj's maybe it's worth it if your not into mechanical work. it's not a very big job to do it yourself and most speed or tune up shops should have a forced injection cleaner. if you use high grade fuel and run inj cleaner occasionally you should'nt have too many problems with that anyway.when i replaced my stockers with 30k+ on them there was no evidence of any deposits on them whatsoever. when i modded my airbox i checked the tb slighly dirty, two or three sprays of cleaner and it looked good as new. what i'm getting at is for 4 hours work tops and less than 50 bucks, if you have the inj's done, you can pay yourself a little over $ 60 an hour and go by yourself something cool for your truck.

 

An induction service isn't really intended to concentrate on the injectors, it's for the intake, valves, and combustion chambers. An Injector Service, where you disable the fuel pump and run pressurized cleaner through the injectors really takes car of that. Like etc. said though, you can achieve similar results at home, without having to pull any major mechanical systems apart. Also, periodically installing certain fuel additiives, (I like BG because I have seen positive results, I have also heard that Tecron? is pretty good), can be very helpful in combating deposits. I try to install a can of BG4400 or 44K every oil change when possible. It is definitly nice to save your cash for other mods, but I pay myself $84 an hour as opposed to $60
