'92 kia pride stalling problem

[isa1023]

Walang rpm gauge po oto ko pero pansin ko hindi constant tunog ng idle nya pag pansin ko na bumaba parang my very slight shaking nang engine (ganito na sya noon pa) with aircon on and off

I think this is fine sir.

IMO, based on your description [SIZE=1](sabi mo ganun na siya ever since eh)[/SIZE], it just means your thermoswitch is still working.

You can confirm this if the radiator/aux fan is intermitently shutting off, or is off on cold starts.
