Hi my CEL is on with P01070 Fuel trim bank 1 showing as the DTC. So far my MAF is showing 2.6 g/s at idle when warmed up. I went thru the PO's service details and couldn't find any mention of the spark plugs or o2's ever been changed out. I have 215,000 kms on it. I was graphing my bank 1 s1 o2 and went I hold the rpms at 2000rpms the voltage stayed around .7 volts and didn't drop below .45v. At idle it does swing above and below .45v but seems to be really slow. I am using the torque app by the way. any ideas? It's driving me nuts

Well figured out the sparkplugs are originals and so are the o2's with 227000 kms. I figure afterthose are done i should be all good hopefully
