UPDATE.
Car got worse, and wouldn't drive long (50-100meters)before it would die and wouldn't start again. No start for like 30-60mins. So basically when engine warms up, it would die.
The next day I called up Customers Cradle Las pinas, and they towed me to their shop. First thing they did was replace the ignition coil. But we still had the same issues. Then they held the car overnight to do some more troubleshooting. They replaced the PGM FI Main relay, which they said was frying my ignition coil because of a short in the main relay. So the next day I had to get another ignition coil! I thought it was all good, as I was driving away it died again. They pushed it back, did more troubleshooting, did an old school check engine light diagnosis and got a code 15, which is Ignition Output Signal. They finally got it, and it was the igniter. Car runs fine again and it's back to normal. Though there were some trials n errors, They didn't give up and found the problem. I thought they were ready to give up and I'd have to buy a new/surplus distributor, but they found the problem. Anyways, just wanted to share the update and process of finding the problem for future tsikoteers with issues with their cars.
