I own a 2002 magna wagon. I bought it a few months ago
I've just had a service done on it. Now I'm having my injectors cleaned off site

How long does it take and will it help??

When i got my injectors done my mechanic (come to you) brought them back the next day and it cost $90 each!

i took mine off , dropped them at a fuel injection specialist , picked them up the next day , cost $140 for all 6 , with new seals , pintles , o rings.
