i got a lsj cobalt that had some wiring issues. i patched up all the wiring and now have these 2 codes to deal with. it has a k&n intake and a catless downpipe. i believe these are the only 2 mods and the guy said he didn't get the thing tuned so im wondering if thats why the cars running kinda poorly
codes are
p0103 MAF high voltage
p0171 lean condition

p0171 is from the intake p0103 could be a bad maf or wiring
