Hello, can't figure out why this caravan with the 2.4l engine has a poor idle and stalls when coming to a stop unless pressure is kept on the gas pedal. Engine runs great except for this. Tested the tps, and seems fine. Also tested the map sensor and replaced, along with the iac valve. Did a compression test, and #1 read 196psi, and the other 3 all read 200psi. There are no codes, not even stored codes.I am thinking of pulling the throttle body off and thoroughly cleaning that. Any other suggestions greatly appreciated.

Cleaning the throttle body and idle air system is a good idea. Any applicable trouble codes?

I'd have to put a scanner on it, that shows live engine data. Maybe it will show idle and idle required, also see what the iac is doing.
