A mate of mine has purchased a tb42e that is running a bit ratty. The only way he has been able to get it to idle and drive is by disconnecting the idle air controller and adjusting up his throttle cable. I was able to have a quick look at it the other day, reconnected the iac and it revved its head off as was expected. So I backed off the cable he tightened and adjusted the air bleed/bypass screw.
It now idles but cannot get it below 1000rpm. I noticed the tps was adjusted to the maximum in one direction. Someone has obviously played with it so I decided to adjust it to see if it would make a difference. As soon as I moved the tps a loud click could be heard from the idle air controller and the engine would stall. I was running out of time, however my mate claims the owner told him that he converted it from auto to manual, my mate has confirmed this as he has found the auto computer.
My question is. What are the differences? I assume the tps and ecu would be different between the autos and manuals?
