I am lookin at buying this supra off CL, dude says it has a 1jz but wont run out past 4grand on the tach. So i did a few searches on here but im mainly finding stuff about the 7m, How hard is it to diagnose and fix this limp mode on the 1jz's, i have no idea what all mods are done because its not mine.. (yet
). ima keep searching the site to see what i can find, i normally wouldnt repost a thread is already been answered in the past im just kinda in a hurry to get a offer on it before it passes by. thanks
