Fixing a misfire on my 23-year-old Ford Ikon

Showed it to a couple of mechanics who concluded that the engine is dead. However, I was not convinced with this diagnosis.

Fixing a misfire by replacing the ignition coil:

A very annoying intermittent misfire had been bothering me for quite a while now. I hadn’t resolved it because it was occasional and the fact that the car does not get used at all. However, for the past couple of weeks, it was getting worse. From being intermittent, it seemed to have become permanent. It would not allow me to accelerate beyond 40 Km/h and whenever the car would be revved while in motion, it would sound like gunshots!

Got in touch with BHPian Viraat13. His trusted mechanic had a detailed look at it and concluded that it was actually the ignition coil that had failed. While it was good news that the problem was minor, the ignition coil for a long-discontinued car from a defunct manufacturer wasn’t going to be an easy find.

However, some research on Boodmo told me that the ignition coil for the 4-cylinder 1.5 Ecosport is the exact same part! Immediately placed an order on Boodmo and had my mechanic replace the part at home. While we were at it, also replaced the HT leads. The car is back to its former self, firing on all cylinders!

The Ikon and its garage mates on a smoggy Diwali evening. No firecrackers this time. Thankfully, no misfiring either!

A video showing the misfire. Notice that no current was being received by the 4th cylinder. The video also shows how after the new coil was fitted, all cylinders started receiving current as expected:
