Re: My poor tahoe q4 has wot problems
Just had the same problem with our 09.... has the boat sat up for any amount of time? I had to rebuild the carb, then the fuel pump fuel filter was starving the carb for fuel. It was clogged. I took the original fuel pump fuel filter out and installed an inline fuel filter. Also you may want to check the fuel line from the tank to the fuel pump, if it is bent it may also be starving the fuel pump....
Also if this doesn t work, make sure you are getting fire to all cylinders by pulling a plug wire at a time, and if the engine starts missing they are firing.
last thing it could be is the gray wire on the Tach, disconnect it, there are instances of that wire shorting out and causing the engine to not run WOT....
I hope this helps...
