    AFR problem at idle

    Hello we have some problem with AFR at idle, above 1-2 hour lambda reads AFR 10-11 at idle and its really rich (tested with external wideband) But if we turn off engine for 30min, than AFR is ok, but only for 1 hour ECT, IAT, charge temp, ecu temp, Bat volt, Inj PW actual and effective all same may be its fuel temp but usually must be lean idle lean after 30 min Log 2018-07-10 8;34;51 pm.llg Idle rich AFR Log 2018-07-10 7;00;47 pm.llg
