Hey guys. After a lot of work on the top end of my Supra I've been spending weeks working out the bugs, vacuum leaks, etc you get with a partial rebuild. Well they're all sorted now except one. I was having a strange issue where the ISCV would only work some of the time, clicking when turned off (as it should) again only some of the time. So I removed it and opened it to find the the stepper motor in good condition.
All looks good, then I looked deeper. Ugh. The plastic thread is snapped, which means it's never fully opening and it's the reason I'm currently getting a very low idle which won't open any higher than 400-500 RPM and turning on the AC kills the engine.
But I know a lot of Toyota and Lexus vehicles of the same age use the same 6 wire stepper motor configuration, only with different housings. There is nothing wrong with my housing, I've run all the electrical checks, so I just need the core replacing. I'm in the UK and I'd have more luck catching an elf riding a unicorn than I would have in finding an actual 7M-GTE ISCV so that is not an option. Does anyone have a list of what other vehicles use the same internals in the ISCV? I can count the number of MKIII's in the UK on one hand, but scrap yards are overflowing with Lexus'.
