Did you reset the TPS(Throttle Position Sensor)?

Might have a leaky IACV, got a vac line loose somewhere.

Also might have to adjust the idle screw if it has one. I'de serisouly check the TPS first though.
how do i reset the tps ??
how do i reset the tps ??
it should be set to the voltage of the old tps
make sure there isnt any open holes on the bottom or back of the TB also
it should be set to the voltage of the old tps
how do i do that ??
switch the tps for your old one. if that doesn't work try positioning it in different ways that's how I fixed mine.

shouldn't need to touch the TPS, I'm betting the gasket......

That's what I was thinking when I saw the title of the thread.
throttle plate could need repositioning. have fun.
IACV is a bit sticky or fucked, mine did this when i put the B16 TB on my skunk manifold. and it still lopes when the water temp is about 60deg its fine when its below that and its fine again when its at 80deg
problem solvered.. the tps came loose when i was driving.. and it moved. so farked up the tps voltage..

thanks for the help guys !!!!
dont know B series TB suit Y8 or not? need some mods?
ive got a b16a TB on my skunk2 manifold on my y8 head and when i first started the motor for the first time, i had to readjust the throttle cable and then adjust the actual idle set screw.
