Re: Re: Re: 5.3 falls on its faceWhere it says "ST FTRM1 (%)" and "ST FTRM2 (%)". Bank 1 is the drivers side, and bank 2 is the passenger side. A positive number means its adding fuel (lean condition) to try to achieve what the pcm is calling for in regards to AFR, and a negative number means it is pulling fuel (rich condition) to achieve the desired AFR. Closer to 0 the better.So the drivers side bank is very lean as its adding a lot of fuel, and the passenger side is rich as its pulling a lot of fuel. Hold the rpms around 2000-2500 and see if the numbers stay the same.The reason I don't think its o2's is because when you unhook them it runs worse, because its losing its live data in regards to actual AFR and running off the tables.
