Guys, so as suggested by you guys to visit the dealership, as my Civic 1.8 Oriel (12k driven) was shutting off suddenly while driving. So today the dealer (Honda Shahra-e-Faisal, Karachi) checked the car on the computer and they said there are no errors or issues diagnosed.
The thing is my car just got the fuel pump replaced under warranty two weeks back after I was stranded on the road. Ever since, the car has suddenly stopped thrice while driving. It just starts and then drives fine again for a day or two like nothing has happened. Then suddenly it shuts off again ocassionally. There is also no warning light showing on the odometer) It's scary because it happens all of a sudden on the road.
Since the dealership has said the car has no issue, I filled up my entire fuel tank with Excellium Hi-octane to see if it's the fuel tank or fuel cleansing issue.
I don't know what else to do. Please guide me, guys.
