Introduction and a question on poor starting.
#15
It still doesn't rev up past 1200 when stone cold.
that is odd.
very odd. even with new FPR.

is fuel pressure rising?, with right foot action.? from say 30 psi idle to near or near 36 psi gunned, (in park) for 1sec. slammed wot? not over revved.

+15 trim hot. why is it adding so much fuel. odd that too. seems the o2 sensor is crying way lean and adding fuel to correct that. -5% is best.(about)

so unplug the 02, drive, dead cold , go over 1200 rpm, .? if yes, now you know why, 02 is fibbing lean or is lean.

on the old 95s, the 02 can cause horrid rich running. with exhaust leaks.
on 96+ its limited, and if to far off the LTFT over limits hit and you get the DTC to match./

the o2 sensor comes on line in say 10 seconds from cold start, ive no idle how that effectt cold running mode. at all.
i thought not until 150F is crossed, but not sure.
but id unplug it. and test.

i bet PO fiddled the bleed to hide, FPR issues, too.. 700 rpm is not super low, and will run there, fix later.
