Salam everyone,
Well i own a Toyota Corolla 2009 GLi..... 100K km's on the clock..... i have been facing a problem recently..... my car misfires / is missing alot..... it started after i removed the CNG Kit from my car..... the previous owner had CNG installed but after buying it from him i never ever let the engine touch CNG..... for the past 30,000 km's i have driven it only on petrol and there was no missing problem whatsoever..... but it all started after i removed the CNG kit recently due to this weird noise the cylinder was making while on bumps.....
Engine isnt drinking mobile oil and the mobile oil is still clean not dirty which was last replaced like two months back..... mobile oil is fine..... radiator is fine and everything.... i dont feel any problems in the performance before and now of the engine apart from the misfire..... hill climb is fine and no issues...... but the misfire problem is just killing me...... i got the engine checked from Toyota Airport Motors.... and they claimed that one of the cylinders is showing low compression..... how and why all of a sudden is the car misfiring and one cylinder is on low compression?..... the car has been running on petrol for the last 30-40,000km's..... i dont know..... i just need some help from experts regarding this problem because the Toyota Airport guys told me the engine will need an overhaul and stuff.... but i dont trust them..... i never trusted them regarding engine issues.... so if anyone can help me out and identify the problem.....
Also there is no black smoke from the back... and Toyota Airport Motors diagnostic computer didnt show any errors related to engine :S
I can sell the car anytime and buy another car most probably same year GLi but with less miles on the clock.... but i m not done with this one yet.... i dont wanna give up.... i m sure its a minor problem and not a big one.... i just need some help from experts.....
Kindly please reply as its really frustrating me cx rest of the car is perfectly fine but this missing problem is killing me..... and has totally destroyed the driving experience and pleasure
