Recently my truck was throwing a P0300 code, random misfiring. After startup I'd put the truck on drive and go to accelerate but there was no response for a second or two. This didn't happen all the time but from time to time.
After some research I figured it was probably a sensor so started by replacing the TPS but this did not fix the issue with P0300 code still throwing. I was going to replace crank sensor next but as luck or no luck would have it the first cold morning of fall my battery lost a cell and wouldn't start the truck anymore. After replacing the battery the P0300 code was gone and now after driving it for a few days the issue has not come back. I'm guessing the issue was low power due to the battery on it's way out.
