993 TT misfire problem

[Utintacciu]

My 993 TT suffers from a cylinder 6 misfire at WOT between 6000 and 6500 rpm, especially on high gears.

Spak plugs are 4 years old and 10.000 miles.

Anybody experienced the same problem?

Any suggestion?

Many thanks

Since it is only one cylinder I would check the one spark plug and the spark plug connector.

Maybe swap the spark plug to another cylinder and see if the misfire follows the plug.

hi there utinacciu, it seems i have a car here with similar problem. i will be looking at it later so will let you know if changing the spark plugs makes any difference to this car. i know number 6 is the most awkward to change. have had cars in the past that have had a set of plugs fitted but it seemed only 5 of them!!

Hi topmech0,

I would appreciate, actually it is quite a long job to check /and eventually change that spark plug. For this reason I decided to do it myself instead of asking to the service, but I haven't had time yet.

Thanks

Hi Utintacciu,Just Swapped Out My Spark Plugs For New And Taken It For A Hard 50 Mile Drive With No Cel Or Misfire Problems. My Plugs Were About 10,000mile Also And Looked Not Too Bad. The New Ones Have Meant No Cel,No Misfires So Maybe You Can Update Me On If You Sorted Yours Yet? And If So What Was The Outcome?
