Question about 1992 Lexus Ls 400
91 LS400 in tip top condition until two days ago. Drove fine to work but at the end of the day starts to idle very erratic, from 150 RPM upto 1500ish and then stalls. Will not stay alive if accelerator is depress. Does this same thing constantly. Sometimes stay idling but once put in gear will stalls. There are no check engine light, no code in memory and no indication prior to it start happening. Checked TPS, MAF, fuel fliter, fuel pump, ECU relay/fuse, fuel flow, air filter, wire bundle in trunk and all the other possibilities out there that I can think of but nothing works. Cleared ECU memory this mrning and car idle fine for almost 40 minutes but stalls once put in gear. Car has 138K and is religiously serviced and maintained. Any assistance will be well appreciated. Oh, I am a "NEWBIE" to this site.
Bad computer. had the same problem sent mine to auto computer exchange in Davie Fl. they reprogramed it . The problem is gone.
