p0102 and p1153 Hi guys my 02 z mods in sig is tuned for the rear o2's and air. Its throwing p0102 which is low input for the maf. I'm running a k&N filter and that is getting thrown away today. Question is that can that be a dirty maf code or is there something wrong with the sensor? The harness at the motor is putting out 12v and 5v so thats good. Also I'm throwing but its not lighting up the ses light, a 1153 code. It may have been tuned out by the tuner but nonetheless will it make any difference? I hear it doesnt really do anything once the cars warmed up it just switches slowly when cold. Both sensors are new so i dont really see them being an issue.....

Btw I was just looking at the code reader and the 1153 code doesnt say anything about an oxygen sensor it says "control air fuel metering" so Im not sure if that stil pertains to an o2 sensor or the maf maybe. As every code ive seen will give a location to the o2 like bank 2 sensor 1 etc.

Hey guys cleaned the maf and all was well. I drove back to college and when parking my car it started to miss heavily. Pulled the codes and at first got p0301 misfire on cylinder that went away and then right after i got p0171 and this one has stayed. The o2 sensor has only a few thousand miles on it and its bosch. The harness is good, etc. I'll check for a vacuum leak but it wasnt really idling high it just was missing bad and on the scan told i could see the drivers o2 sensor running at .015 v which I guess is dumping fuel into the motor because it thinks its lean...... Any suggestions could it be a bad maf?

also fuel filter was just replaced 5k ago and the passenger o2 sensor is reading just fine fluctuating like it should between volts whereas the drivers side is steady around .015-.025
