Kindly assist me guys. I performed a servicing exercise on my mitsubishi galant 2003 model on Saturday.
I changed the engine oil, oil filter and also washed the plug with petrol. Afterwards, i noticed the engine has not been performing well cause it keeps giving me a misfiring sound before it swerves into full motion after a change of gear.

Will appreciate your input.

Check your air flow meter.

Kia Nigeria aka Dana Motors did not get the full memo

Inception:


My brother,

The vehicles sold as brand new for the Nigerian market are :

1. Basically watered down variants of the American counterparts ( imagine a 2012 KIA optima with only driver and passenger airbag, Manual seats, OBD 1 capability , and a mere ABS system only?!, where the american spec comes with a more powerful engine (GDI), driver, passenger, curtain airbag as standard, Bluetooth capability as standard...

2. Most car parts( Engine, Transmission) you get today are sourced from the US/canada, compared with fewer ones sourced fom Japan/ Korea.

This implies the ones coming from the Asian countries to be more Expensive( although they are usually with much lower mileages and in some cases better quality )
3. More as i remember...

Check your air flow meter.

The car was borrowed for a week now and driving it today, didnt notice the jerk. Will test drive again tomorrow and i pray its not d airflow cause i don taya to dey change dat flow meter.

Finally, I fixed the car.

The problem:

One of the plug was faulty. The head and bottom of the plug were no longer in connection due to weakness therefore the engine was receiving partial energy.

I had to change all 4 plugs and the engine came back to normal.

Lesson learnt:

Don't tighten the plug to the engine too hard. I think i over did it when i serviced the car myself thus causing the damage to the plug. It took the professional hand of a mechanic to remove the bottom part of the plug from the engine.
