How to clean the throttle body the easy way ?

Im experiencing poor idle and unsmooth loadchanges. No codes are schown except 12 and 55 and i couldnt find a broken Vac line either. After reading up here, cleaning the TB seems to be an option. Would it be alright to remove the rubber hose in front of the TB and just spray a can of carb cleaner into it while idling ? I have no access to a lot of tools right now and this could be done with a screwdriver and a can of carb cleaner. Any other options maybe ?

Thanks

Matt

P.S. Car is a 92 Daytona 2.5 TI

Remove the TB from the vehicle.
A couple of bolts, electrical connectors, vacuum lines and cables.
Remove the AIS and clean the pintle and bore.
Loosen the screws for the AIS before removing the TB, if they are tight use a micro torch to heat slightly to loosen the factory loctite.
Replace the gasket.
Check/adjust base idle and reset AIS.

Re: How to clean the throttle body the easy way ?

but you'll need the correct TORX bit to get the TPS off; and sometimes they can be a B*TCH to get off ...

NAJ has detailed the best way ; however, you may have some success with just spraying ~1/4 can carb cleaner down TB while high-idling

before doing that, inspect the TB bore... sometimes they are VERY dirty ; if thats the case then yur AIS pintle etc are prolly DIRTY too, then yu'll need to pull and clean as NAJ suggests

Thanks

Thats the problem no torx bits for me right now. So i hope the easy way helps or at least lessens the problem until i got time to remove and soak the parts. And resetting base idle with the danger of a frying surge sounds a bit scary to me. Not a lot of spare parts at junkyards here in germany for these type of cars(more none at all ;) ).

I have found soaking the coked pieces with Mopar rust penetrant for 15minutes and following with a can of carb cleaner and a toothbrush to be very effective for cleaning.
