so i did a swap into my 94 eg with a b16a, so i had a smooth idle after the swap but then i had to remove the heater core hoses to replace the T bracket cause the one i had didnt align properly. an after that i got a bad idle.

i bleed the coolant system a few times an it doesnt want to get better, so i clean the IACV with cleaner an try it again an it still has an idle that goes up an down.

what else can i do or check.

i check the voltage on the iacv plug ani got a 12.34,an when the car was on i unplug it to see what it did an the car died.

any help with really help me out thanks

 

Check for vacuum leak. Spray carb cleaner between TB and mani. All around. See if idle gets affected.

 

okay ill try that soon.

 

so i check for a vacuum leaks an didnt find any.
but the weird thing is that i disconnected the Tps sensor an the car idle smooth now.

so it running with no tps or map sensor cause i dont have a tb with both sensor for the b16a.
