Need to pass smog check, code p0171 keeps coming up, no vaccuum leaks, fuel trim on bank 1 sensor 2 is up to 99% bank 1 sensor 1 is 25 % at idle, system showing open loop only, upstream 02 sensor showing about.25 volt, downstream at.98. Tps showing +4 at idle. .I changed a injector on cyl 7 a while back that I got at a wrecking yard
. Is it possible from these numbers that the injector I got is either the wrong one or bad?.I've checked about every sensor I can find a test for and haven't found anything out of range. Never checked downstream 02. Any help to narrow this down or pinpoint would be appreciated. Thx
