No, 18.5 at idle, but cruise speed is 14.7, now if I tune with gen2 until 14.7 at idle my fuel trims turn rich 60 and smell too much gas and cruise speed is 12.7. what's wrong?

Hi.
The fuel trim at idle it's 95-105, and the wideband reads very lean 20-22, then I tuning with the maft and the wideband reads 14.5-15.5 but the fuel trim reads 65 and 02 sensor reads .7v-.8v , this is very rich for the ecu,right?
so what is wrong?
thank you for you advice
