Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

1999 Chevrolet Lumina Owner Comments

problem #1

(reported on)

Lumina LS 3.1

  • Automatic transmission
  • 100,000 miles


Perhaps approved by the same executive as the clown who approved of the plastic intake manafold gasket concept, GM did it again on the GM 1999 Lumina 3.1 V6 and other motors by selecting plastic for use in the fuel injection spray nozzles. However, special assists go to the idiots that made the fuel injectors so hard to get to, so hard and expensive to clean, and so hard and expensive to test, rebuild, and/or replace. lists several fuel injector ultrasonic cleaning services that charge about $90 all told for cleaning. On/off labor is at least $500 to remove the injectors to mail out for cleaning. You are looking at $75-150 each to replace individual injectors that are too far gone to clean/rebuild. They are under 1200 lbs of fuel pressure which blasts you like a fire extinguisher with raw gasoline unless you have the foresight (or you've read the manual) to depressurize the system before working on it. Fortunently I was wearing my $300 presciption plastic eyeglasses at the time. Talked to mechanics it is a routine problem.
