i'm currently having a problem with my '89 Corolla XL. For about 3 weeks, napapansin kong kumakadyot siya, even while at 1st or 2nd gear. On highways going 60kph and above kumakadyot din, but it seems more prevalent sa primera/segunda.

Last weekend the problem got worse. It didn't used to die while idling, pero ngayon napapansin kong biglang bababa yung RPM, then dies out.
i've tried raising the idle RPM pero namamatay pa rin. Right now i'm thinking that the kadyot is just a symptom of this, hindi lang siya namamatay 'coz i was stepping on the gas.


OK pa naman yung hatak, If anything the response even got better after a visit to the talyer.

Kakareplace lang ng
- sparkplugs
- contact point
- clutch lining(eto ang hula ng mekaniko since kumakadyot pag primera, turns out mali pala. oh well)

so ang suspetsa ng mekaniko is a dirty carb, which may have some credence since all this time, pieces of the rubber hose( connecting the ait filter housing to the front of the car) had been getting sucked into the carb all this time. Some of them have melted onto the air filter
i've already tried cleaning it with a carb cleaner, no improvement.


What other causes could there be, aside from the dirty carb?
