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.

problem #1

Sierra 1500 SL 4.3L

  • Automatic transmission
  • 273,200 miles


Code 51, Won't idle sometimes, loses power while driving. At 60 mph will start to buck and speed drops off then will pick up again. This will happen 3-4 times clear up for a short time then start again. While coming to a stop light engine won't idle, as you take off engine surges, rpm jumps up and down, as it slowly takes off it will clear up around 30mph. As you drive around 60 mph you will feel a slight hesitation the check engine light comes on. When this happens it will either lose power or it may clear up, light goes out. Problems are random. One day it may run with no problems but the next day it won't get out off the driveway. All sensors, EGR valve and distributor have been replaced, New plugs and wires and coil have been replaced. There are no vacuum leaks. New timing chain and intake gaskets have been installed. Fuel system psi is correct, new fuel filter and reg replaced. All voltages and grounds have been checked. ECM has been replaced.
