I still have problems with my corolla.I retrieved the following codes yesterday.
P0171(too lean)
p0100(maf circuit)
p0101(mass/volume circ. Range perf. Malf.)
p0110(intake air temp circ. Malf.)
p0171 again as the 5th code
i pulled a vacuum line off going to the aftermarket cruise control that had been taking on chemicals(smelled like stale fuel) because it was spongey and I thought that might be the issue but after plugging the 'T' where in went into the valve cover intake, it still threw codes. It seems to run okay, sometimes have to try to start a second time when cold. Worried about long term effects/gas mileage. Will a repair manual from a typical auto parts store explain how to test fuel sensors, maf or map sensors and or circuits?
