if you look in that last picture, do you see the Red rubber cover over the alternator wire? right behind that there is a hose which goes into the manifold. just unplug that hose, and spray it in there.
I think you can spray like that through the engine is off Sinh, and really clean the throttle / + s to leave for 5-10 minutes to evaporate all. Remember this is an aerosal jet fuel at least 20 cm from the battery. Danger, if the motor is running. The high power filter cleans all incoming calls and heads, bored, etc.
I'm pretty sure when i used the UEC, i sprayed in half the can, you let it soak in, then start the car and spray the rest. It helps having two people as the car will want to stall, so one to spray and one to keep revs up
you'll know if it worked too, my car chucked loads of smoke from the exhaust
Take of the "Torque Box" up near the throttle body (3 PCV type hoses, 2 bolts, 2 hose clamps) and spray it straight into the throttle body. You'll have to hold the T.B open with something (a big screw driver wrapped in a rag works wells) due to the electronic T.B. Leave it for 5 - 10 mins, basically as long as it takes you to put it back together.
