Cylinder 3 misfire

Hello,

My name is Denis and I'm from Romania.

I own an VW Golf V from 2007, 1.4 TSI 140 CP motor.
Already I have changed the spark plugs and the coils for cylinder 3 and 4 but still after scan I have this error :

000771 - Cylinder 3
P0303 - 000 - Misfire Detected - Intermittent
Freeze Frame:
Fault Status: 00110000
Fault Priority: 0
Fault Frequency: 3
Reset counter: 255
Mileage: 150420 km
Time Indication: 0
Date: 2000.00.00
Time: 18:13:10

Freeze Frame:
RPM: 1175 /min
Load: 40.0 %
Speed: 0.0 km/h
Temperature: 9.0°C
Temperature: 1.0°C
Absolute Pres.: 1020.0 mbar
Voltage: 14.351 V


Readiness: 0010 0001

Also my turbocharger needed reconditioning a couple a weeks ago,when I have changed also the filters and oil.

The problem is when I start the car it shakes for a minute and the check engine light blinks after that it disappers. For a couple of times the check engine light stayed on for 2-3 days .

Can you help me with this error and a solution to my problem:
000771 - Cylinder 3
P0303 - 000 - Misfire Detected - Intermittent

Thank you.

Hello Denis,

Please post the complete Auto-Scan. That engine wasn't sold here so the scan should help.

Excessive carbon tends to build up on the back of the Intake valves causing misfires so you may want to rule that out as a possible misfire cause. Fuel injectors fail as well - but without knowing the mileage on this vehicle I wouldn't want to suggest replacing it yet.
