I done tons of research on why my s2000 wont start on the first try after sitting outside overnight and cannot come up with a solution. I did a: map whak, 10-30 oil change with m1-104 filter, cleaned air filter, replaced an o2 (code po131), changed the serpentine belt, spark plugs and inspected the coils, perform ecu idle relearn and reset, changed the battery.. Holy cow lol all in one month. Anyways the car starts fine in the garage even after sitting for 3 days. the minute its outside over night, it stalls on first crank than starts for the rest of the day. Temps are 87 in the after noon, 40 at nihht. Learning ecu problem?
