idle question

[1SlowCA18DET]

ok i already tried cleaning the thing under the throttle body, made sure timing is good, and checked the gap on the plugs. Now evertime the car is on it will idle straight until i come to a stop then i would have to keep it alive. what could be the problem. o yea all this started happening after i swaped to a ka throttle body. the vaccumn is good and the nipple off the throttle body is blocked off.am i suppose to switch over the tps sensor cause it runs fine just wont idle.

you should be using a CA18 TPS.
