Cold Start System Testing (hard starting)

[Bossard]

On my Celica with a 2.2 litre engine I have a rubber hose that connects from the air cleaner to the throttle housing. It is attached on both ends with a hose clamp. If I loosen the hose clamp at the throttle housing and remove the hose you can see the butterfly plate inside. You can rotate it open to spray starting fluid internally. Also, you can just spray starting fluid into the air cleaner as this will drawl into the throttle as well. Just give a quick short spray though, you don't want to overspray too much. I imagine your MK3 will have a similar configuration.
