Took the car out last night for a run and noticed that on tick over there was a slight judder through the car, I got out and went to look round the back of the car and noticed it sounded to have a misfire on the of side engine bank ( near side tail pipe) When i got back in the check engine light had come on. Apart from a rough idle the car seems to run fine. Is this the sign of a failing coil pack or something more serious? thanks for looking every body.
 
The easy thing to check is the MAF. From there, move onto having the codes read to identify the culprit. Could easily be a coil as you suggest, but get the codes read first in case it's something less obvious.
 
Took car to indie yesterday and its not good news. It has low compresion on cyl 6 so looks like a scored bore. The car has only done 63k and has a low temp thermostat fitted. :sad:
 
Sad news Chuck' but iirc at least you're still under warranty.

Let us know how you get on.

Good luck :thumb:
 
Just got back of holiday and engine is out of car and having six new steel liners fitted under warrantee and an upgraded ims bearing while engine is out of the car, so fingers crossed it should be ok for a few more thousand miles when it comes back.
 
If you wouldn't mind, could you please advise of ball park costs for this? It seems all the Carreras end up requiring this as some stage and I have heard various wide ranging prices.
 
Glad its being sorted. Out of interest who is the warranty with ?

Who is doing the work?

Who is the warranty with?
 
The warrantee is with specialist cars Malton who I bought the car of in december so they are taking care of all the work. There service has been absolutely faultless so far, would recommend them to anyone.
 
I thought that was scaremongering from Baz as there were no concrete facts or stats?
 
It looks like the steel liners are used in porshe club racing as they can't modify there engines and they don't seem to have any issues with them. What's the life expectancy of the steel ones in a road car?
