Urgent help required!! Somedays ago in a stormy weather, the cng pipe got loosed. Since then , may be due to cng improper tuning or less or more cng intake, sometimes car on cng gets even more pick then petrol and sometimes rpm start dropping and result car stops.
The engine checklight sometimes gets on, and even Sometimes when the car rpm are dropping , when I try to switch off the ignition I'm unable to do this.
Mechanic told me that go to Hyundai sajjad motors and check the car on the scanner, may be this is due to faulty wiring or sensor.
Anybody!!! Help me diagnose the issue.
