Can someone help how to fix the following code check engine# 26, 71 transmission# 63, 67

randal

The 26 is air-fuel rich mixture and 71 is EGR malfunction. So, I would do some searching into these two subjects.
What year, model and miles?

Here is a list of OBDI codes -> http://www.lexls.com/tutorials/intro/codereading.html

EGR could cause lean, ECU would compensate by making it fat, <--- old school term.
Was all this a sudden onset? If so could be the ECU caps issue.

Thanks for the advise guys... I just barely purchased a 1991 Lexus ls400 a lil over 300,000miles but it runs really strong all original nothing modified everything on the car works minus the obd1 code problems.... Next weekend replacing clutch speed sensor and solenoid#2 on the transmission.... What transmission oil are u guys using or what good aftermarket oil is good out there?

I thought the Power Steering specified Dexron.
