What causes a Toyota celica to stall while in idle?

Answer 1

if yours is a manual make sure the clutch is not dragging, if its not and your problem is purely at idle look for any vacuum leaks(cracked /missing hoses) you can do this by spraying carb cleaner around the intake fittings while the motor is running, if a leak is present the carb cleaner will in-richen the fuel mixture and the idle wis raise. if you sprayed evrey fitting and havent found a leak then its time to look in to what controls the motors fuel.

MAP

TSP

AIC

these three components work together to create the ideal fuel to air ratio for the motor in different conditions.

first pull off the air in take hose, be sure the butterfly valve moves freely, clean area with the leftover carb cleaner. now that you have located the butterfly valve find the AIC (air idle control ) is bolted just below the butterfly valve. over time carbon and other foren objects clog and block that valve, remove and cleane with carb cleaner, re install the ICA and most of the time this is the solution

good luck
