Misfire and fan on when hot - 308 (2008-2013)

First of all, Hello,

My Vehicle 2009 1.6vti Comfort Manual

When the vehicle starts to idle after warming up, it misfires and then turns on the fan and gives an exhaust emission warning on the screen. When it went into malfunction, when we connected it to the computer, P1340 was giving a 4th cylinder combustion disorder malfunction.

Since the vehicle was used with LPG by the previous owner, the valves were exhausted and the vehicle was burning oil, so the engine was overhauled and LPG was removed. Spark plugs, coils, chain seal kit, thermostat, circulation etc. have been completely renewed. Injectors have been checked.

After that, when the start is made, misfire and fan switching continue, because only the compressors are on, it does it from time to time regardless of cold or hot.

Then the brain and plumbing were checked and no problem was found.

Has anyone had such a problem?

Thank you in advance for your help.

Hello, sir, is there an error code in the vehicle now? there are also eccentric lubricating solenoid valves, it may also be caused by them.

Hello, When the vehicle starts to misfire, it gives P1340 error. Tried eccentric valves, problem not solved.

Mrb, you probably have a compressor leak in your vehicle.
