Appx 1 yr ago timing belt broke. Friend starting new garage replaced and commented timing was adjusted. Recently checked to find set at 5 BTDC not 15 BTDC. Adjusted to 15. Week later find that RPM’s fluctuate after vehicle warms up, runs like dog. Replaced fuel filter, added fuel stabilizer, cleaned MAF Sensor, dusted out distributor and Cam Position Sensor. Operates normal for day or so then returns to fluctuating.

Check and test the IACV-AAC valve and Throttle position sensor.
