Re: no power	Sign In

your vehicle is experiencing a lean condition.Fuel pressure would have to be measured under load or no power condition.It could be faulty/weak fuel pump.Faulty or dirty injectors.It could be ignition related/pcm or sensors....take your pick.The low power uphills sounds like fuel pump.Tests would have to be done.P0300 just means that something is disrupting the air/fuel ratio to cause a missfire.Fuel pressure would have to be monitored while driving.
