7MGE MA61 throttle cable

What he said. Check all hoses, pipes and fittings between the AFM and cylinder head. 7M's are notorious for developing leaks in the inlet system as they age.

Bah throttle cables are for girls. Tie a bit of packing tape around the throttle pivot and run it across the engine bay and into the cockpit. Accelerate by hand . (this was a wrecked supra in a private paddock..)

The fact that you did that is just awesome!

Got the throttle cable sorted out for the moment. Now I have more issues. At idle the engine is hunting (revs climb and fall, climb and fall) Advice from Allan had me pull the idle control valve out and clean it, almost seemed to fix the problem but then after about 30 seconds of idling (a little high, but steady) it started again. Anybody got any other ideas for me?

I had this exact same problem with my 7m-gte, turned out to be a crack in my accordian hose, right before the turbo. I know your's is just a 7m-ge, but check intake piping after the AFM for a leak.

Yup, i had the exact same problem. I located it to be my ISCV, it was stuck open as the coils inside the ISCV were stuffed. If you pull the plug off the ISCV and nothing happensto the idle, then crimp the vacumm hose leading to the ISCV with your fingers and the idle should fall. If this happens, its your ISCV thats the problem. Start looking for a second hand item.

...And if you find a spare one let Neg Boost know aswell

Well we managed to fix the problem, thought not exactly sure how We think it might have been the ISCV not getting power. Anyways, being that its sorted and ive already bought another ISCV if anybody is in need drop me a PM. Thanks for all the help and ideas people.

Just for info... there should be two 7M-GE throttle cable lengths, one is for the IACS 7M-GE (longer), the other is for the non-IACS 7M-GE (Cressida) and 7M-GTE...
