I've got my injectors out, and as opposed to replacing them I'd just like to have them cleaned professionally. I need it done by next Sunday when I'm putting it all back together. Essentially I'm replacing the valley pan (coolant leak). I'd like to bring them somewhere locally just to make sure I get them done in time. I'm north of Chicago, betweer Chicago and Milwaukee. Lake County Illinois. Anyone know where I can have my injectors cleaned around here. I've looked online to no avail. Thanks guys.
