2001 Monte Carlo 3.4L
107k miles

I just did an OBDII ll Live Data Stream and was wondering if anyone could explain the results a little better. For the most part I know what info is being displayed in each section. Im just not sure what "ideal" results would be. Or if i got good or bad results.
This is the Live Data Stream while idling. Car runs fine, from time to time there is a slight sputter while idling....

DTC_CNT = 0

Fuelsys1 = CL

Fuelsys2 n/a

Load_PCT = 2

ETC F = 189°

Shrtft1 = 0

Longft1 = 12.5

Map inhg =10

Rpm = 700

Spark adv 19

IAT = 111°

Maf = .442

TP = .4%

02s ?


Thanks for any info

 

The LTFT is kinda high, odd that the STFT is perfect lol. IIRC the max LTFT one can have is 16.4, just for reference.

I know my L67 has around 21 inhg when read from a vacuum gauge, but the Aeroforce reads 10.5 at the MAP. If you're actually running with 10.5 inhg from a vacuum gauge, then there's an issue.

O2's are to be read at wide open throttle. As for the sputter, check your wires and plugs, normal tune up things. Could also be the MAF sensor acting up.
