A co worker is having problems with his 01 Lexus IS300. It is throwing a CEL for code P1129 for the Electronic Throttle Control System. It seems like a general code for the whole system not a part of it. They can't drive the car as is since the throttle does nothing. Anyone experience something like this themselves or have heard of this issue? I know I can join a Lexus forum but I will try that as a last resort. Thanks.
