I am wondering if i should take it to dealer or just do it myself. (Throttle Position Sensor)
Lets shoot some info. My 1999 Lexus gs300 goes into limp mode after i drive it for a couple minutes for example.... The check engine light, VSC and VSC off come on when the (limp mode) starts. then i press on the gas and it doesn't accelerate or rev untill i pust to the floor and even then, it only goes to 2000 r.p.m.s.( not fast) about 5 mph.

So is it the accelerator position sensor, Accellerator Pedal sensor, Throttle position sensor, o2 sensor or cracked intake hose?????

Has anyone else had this problem with a solution ????

here is what the dealership said.
Pulled engine codes (P1120 Accelerator Pedal Position Sensor) Performed Lexus diagnosis procedure. Found when warm, accelerator sensor goes open. Suggest to replace Lever Assy, Throttle Part Number 22060-46010. $336.76.

I just ordered it and its coming tomorrow. Hope its easy to install. I was looking for a (how too) on line. but couldn't find one. if anyone has instructions can you post it please. otherwise ill give it a shot tomorrow...

Mine just broke 100,000 miles on Monday and the most serious thing that ever happened is a broken a/c comp. If you dont have too many mods just keep the oil changed and the annual tuneup. 2JZGE's are pretty reliable.
