[joe.wilsonjr.12]

Hi. In need of help. My truck starts and will drive. But then either stall or bog down and have no power. It dont throw any codes either. I replaced the throttle position sensor. And its still doing the same thing.

Fuel injector cleaner does not work, period. Their are so few on the market that do any good. If you narrow down that the injectors are the problem, have them professionally cleaned or replaced. The first thing I'd recommend is do a fuel pressure test. We need to know if your pump is pumping, and filter and line up to the injectors is strong/clear. Second have your catalytic converters checked at a shop. They'll pull the front 02 sensors and check for back pressure, and possible blockage. Report back what you find.
