my service manual says to set it at 15.2% the scantool software i am using will jump from 15.3% to 14.9%
will that .1% make a differance, i am still having a issue with the Throttle cutting out, holding the pedal when this happens trac lights come on.i did change my tps,even
removed my tps from my tundra just to make sure i didin't get a defective part,same part number is used.
any one have any idea?thanks

Why are you replacing the TPS? I don't know what book you are reading or getting the info from but the spec on TPS is 14.4-16 %. Have fun replacing it and don't strip the bottom screw

i am using the information from a mitchell repair cd i purchased from ebay.so anywhere between 14.4 and 16% is ok?

Mitchell repair manual is not 100% correct sometimes. You will need to get the lexus service manuals.

does anyone with a service manual for a 99 gs400 have this information? thanks

This is the information 14.4-16% of throttle. Lock it down and call it a day. What other info do you need?
