P1340 - 01 error code

[Pattyg]

Hi all

I’ve just bought a lovely 1999 2.5 Boxster and really wanted to join the forum.

Unfortunately my car is throwing up the above error code which I understand is - Timing Chain out of Position Bank 1.

Car is fine idling when cold but there is a de table slight misfire at idle when the engine is warm. The CEL also goes on and off but will come on mainly after the car has warmed up.

I’m aware this error has shown on other member cars and would like further info as to what the issue may be or was your experiences.

Many thanks in advance
