I have a gen5 3.0/stock rockers again/full size IC/ 42s/N* and s1x cam
My issue is and has been the start up driving of my car. It will start , rev up and down for a few secs and settle in. Start to drive and the LTFT rises to 16.4. Sometimes this happens right after you put it in Drive or upon de-accel. Then at idle it causes a surge and sometimes stalls. Continue driving and its fine. NEVER comes back again. Trims go to 0.7 to -3.2 while accel and cruising.
i filled up my data logger to 71% with scan data, used eddies ( reset trims before and after) and my trims are tighter and tighter, but this fluke is still there
I went to Fuel>General>startup AFR vs ECT but I dont see what "decay" would do
SO then I went to Open&Closed Loop>and went to O/L AFR and dropped the AFR from 32* to 158*cells to 13.2 to see if it helps
Im probably not even looking in the right place
Its not a vacuum leak, I had my motor apart and did the lines recently myself.
Is this my o2? or something else?
I tried to add fuel during warm up but I think Im doing it wrong
