SOURCE: audi a4 1.8t random miss fire

Check out the AboutAutomobile.com site for NHTSA complaints. I believe there was a defect in the cylinder heads for this engine. The redesigned heads have a different suffix letter than the stock heads.

For a time, the Manufactuer was paying for the repair.

IF THESE SHAKES ARE HAPPENING ONLY WHEN THE CAR IS AT COLD START THEN U MIGHT HAVE A MINOR VALVE PROBLEM.THE VALVE HEADS DUE TO NO LUBRICATION FROM THE FUEL THEY TEND TO GET DIRTY AND NOT SIT AT THE CYLINDER HEAD AS THEY SHOULD.REMEDY IS FIRST A GOOD TEST DRIVE AND BY GOOD I MEAN REVS OVER 4000 AT LEAST.IF THE PROBLEM PERSISTS UMIGHT HAVE TO DISASSEMBLE THE CYLINDER HEAD AND CLEAN THE VALVES MANUALLY.
UCAN SEE WHAT I MEAN AT THE PHOTOS BELOW

Have you tried disconnecting the battery for fifteen minutes to reset the computer. It may take another 24 hours of driving after reconnecting to reset all of the sensors properly.

Ny nissan 1994 cefiro model has what you call hiccups when driving, fuel pump has been changed including spark plugs, change oil done, cleaned the air intake as well, still has the hiccups?


Did you change spark plugs wires? fuel filter? I do not know if your car has MAF sensor, but if it does, clean it. Use CRC- Mass Air Flow Sensor cleaner. also check Spark Plugs Gap and coil (s)
