Passed state insp. said i needed new fluid cleanse on brake fluid, (infected)" my injector bar needs fumigating, GUESS what, the cabin filter I don't have needs to be replaced! Also a radiator cleanse. ALL OF WHICH THEY DO?


Now i would like to know if there is someone on here to tell me of a fuel injection thing to do. 137000 miles. 2003 TB I6. Thanks ahead.

On a full tank of gas, pour an entire 16oz. can of Berryman B12 Chemtool into the gas tank and drive it like you stole it until the tank is empty. Do this every other oil change or 5000 miles, whichever tickles your fancy. If it's really bad, Liquid Moly makes a fuel system cleaner that's supposedly the top of the pops, and has the documentation to back it up.

Where did you get the state inspection done? An actual shop or one of those franchised quick change places?
