I'm a little skeptical cleaning like this but it's worth a try.

You need at least 3-4 days if you have to send them out.

 

Super easy man, in about an hour and a half you'll be done.

 

Does a 3 year old car really need there injectors cleaned?

 

I agree... thats why it's worth a try.

On the other side... it may just be better to have them done professionaly off the car. That way they can do flow tests as well.

 

How many miles on the clock did you guys have when you cleaned them out?

 

My car started showing symptoms in the high 40k mile range. From what I have observed on the forum most show idle misfire symptoms from the high 30k to 50k range. But, there have been cases with lower and higher miles.

This is all from my memory and observations over the last year or so.

 

Had mine done at 35k.

 

Soo...take out injectors..spray with carb cleaner..then replace?
