Hi. I get the the trouble code 43, and just recently when I start the truck, it wont start up right away. It takes about 3 times to get it to start. Also after I stop at a light, and I go again it will go but it starts to hesitate going faster than about 30 mph (or when I really step on the gas). I dont know if its related, but it keeps showing I have low voltage on the battery. I put a volt meter up to the battery, and I was getting ~12 volts (engine off).

This has recently happened, and I dont think its related to the knock sensor since I have grounded the knock sensor a few months ago.

For what reason that you grounded the KS the sensor has a job to do within the engine management system? Are you aware of this
