guys my car has been acting up lately... so far this issue has only been observed while car is idling and stand still. So while idling, suddenly the engine dies for a second or two and then sometimes it comes back on its own and sometimes it doesn't. There is NO CEL, it feels like if somebody quickly turned the key to off position and then put it back to on position.
I am using cng in car also and so far i think it has happened both on petrol and cng (will confirm this again)
I searched over internet a bit and it seems it could be loose ignition connector or main relay.going bad. I tried to bump the steering and wiggle the key but nothing happened, its usually random... And it happens suddenly, not that engine first drop rpm then die, and the sound of engine turn off is same as if you turned it off using key
Second problem which happens sometimes is that when i convert from cng to petrol the engine start to lose power and start doing missing unless i convert it back to cng. To make it work, i have to press accelerator pedal hard at 3k+ and then switch to petrol. I think it could be due to bad fuel filter which i have never changed?
