1996 850R resetting ecu doesn't clear fuel trims

[jacsil]

i installed a new battery (warrantied the old one) and tried to check for a draw using the multimeter set to mA milli amps and found it to be .002 which i think is ok.

there may be a drop off between the alt and battery when the car is hot of .2 i might add a thicker cable. I dont think this would cause the current issue of o2 sensor showing lean most of the time, ltft around 21.1 and stft not showing up 99 percent of the time. the car running in open loop. the maf readings have gotten higher.

the last two times i reset the ecu and got the ltft and stft to work along with the o2 sensor working properly. the o2 sensor started running in a lean range .22 to .oo5 and the stft went to 0 and the ltft went to 21.1. this happened when the car had been driven for a while and i let it idle for at least 5-10 minutes.

my front bakes especially driver side need rotors and pads. could extra pedal travel cause vacuum issues?

also the two intercooler hoses attached to the radiator and one other hose are origional and in poor condition I have purchased hoses and will install them hopefully tomorrow. the hoses can be easily squeezes shut with one hand and two feel like they have internally creases in them from where the sit against the radiator housing.
