Dear Mates ,

I would like to thank first Admin and mates on the forums for the valuable help given before

for this time I have a serious issue with my car :
1-/ Description : difficult start , it feel like fuel pump , after starting the car idle normal , then when warm and drive some times it fine some times when I push the car shaking and Engine work on 5 Cylin only + difficult to go on high rpm ,changing gear till 6 ok but when going to 7 gear and rpm over 4000 tr / min difficult and more shaking , then PRND flashing .

drove the car manual mode , and pushing all gear to 3500 tr/min when changing from gear to gear , it drove better to 6 gear then more shaking going in 7 gear so better stick to 6th gear

another remark : when car is ok working on 6 cylinder and idling perfect pushing petrol down to max some times to Kick down , Rpm wont go over 5000 tr/ min , only with time and slowly increase and just to 6000 rpm


2-/ Diag done :
Engine
16689 - Cylinder 5 Misfire Detected
P0301 - 35-00 - -

Transmission

18151 - Clutch Slip Monitoring: Signal too Large
P1743 - 35-10 - - - Intermittent


3-/ works done :


switched coil 5 , switched spark plug 5, switched injector 5 , always same error : misfire on Cylin 5 , so it isn't a coil nor spark plug , no an injector .

even when I suspect my fuel pump : how it can give misfire only on Cylin 5 why there are no intermittent misfire on other Cylin ?

if its a valve : the car wont idle perfectly and even drove inside town with D drive perfect very smooth ! for 3 hours and then parked and then tomorrow goes crazy again !

Any help please , I am travelling with it and in middle of road and dont know what to do !!!

you help will be very welcomed and appreciated

Regards
