Idle problems

I have a civic 1992 with a b18c1 motor. I had a bad detination and it blowed the cold air intake off of the car,and now it wont idle right. it goes from 1200 to 2400 and goes up and down up and down. How do i solve the idling problem. (i tried a map sensor and it still has the idle problem)

hows your Tps? a bad TPS would do this at times. check your vacuum lines.... did you also check that you put the right plug on the map sensor? the tps and map sensor plugs look the same so theres a possibility that theyre on backwards.

Im running nitrious and i had the wrong fuel jet in. The car had a bad detinated bad out the intake now the idle goes from 1000 to 2100 and back and fourth. Idk i know the map sensor is good and imm pretty sure its not a vaccum leak

I took my thottle body off and it turns out the detination bent my butterfly into a horseshoe shape, and thats why it had a irdical idle.So anyone with a bad detination should look for a bad butterfly if your idle bounces up and down up and down
