Ok guys i was able to work on the supra on saturday and thought id might share some info about whats happening now. well i am able to drive it now but not really and the idle is still messing up. so when i drive it i have to tap on the gas a couple times before it will go, but when i try to shift gears it dies and i have to tap the gas again before it will go again.
And when sitting still when i try to keep it at a certain rpm, it will stay there for a second and then go back down. then when i hold it a wot it wont even do anything it will just sit there and the rpms wont change.
And the only code i am getting is code 52 which is for the knock sensor. but i have another question, instead of tapping the block to put another knock sensor in, can i just splice the two knock sensor wires together and connect them to one sensor. and sorry for the long post. i really appreciate everyones help.
