You have to add ST and LT together at a moment in time. Do that at idle and again at 2,000 RPM

 

Now it says closed loop. Blazer seems to be in limp mode as now it wants to idle at 2k rpm. Short term fuel 1 is -0.8 to -7.0 and long term fuel 1 is -18 steady.
Short term fuel 2 says -1.6 to -10.2 and long term fuel 2 says -18 steady.
MAP (psi) 3.6

 

I can’t seem to get steady reading as it dies if I don’t feather pedal every few secs

 

Short term 1 says 21.9 long term 14.1 now

 

Short term 2 7.0 long term 2 24.2

 

Now reads short 1 11.2 and long 1 25.0

 

Now says short term 1 0.0 and long term 25.0 short term2 is 0.0 and long term 2 is 25.0

 

So far both short terms 1&2 say o% and both long terms are fluctuating 25.0 and 22.7%

 

It did a freeze frame for the code P0341.
Fuel OL
Load_PCT % 1.6
SHRTFT1 % 0.0
Longft1 % -0.8
SHRTFT2 % 0.0
Longft2 % -1.6

Live data still saying CL 0% on both shorts and 22.7-25.0% on both longs
