Hi ALL
The problem of idling and misfiring on a cold start is sorted now i had the head checked and installed new valves ,then all is sorted However there is only one problem left ......there is a grinding noise on a cold start and it lasts for seconds and if i switch off the engine and start...
No its only misfiring when the engine is cold,when it reaches the operating Temp all is fine ,and all coils are working fine ,No engine light the dashboard
i have also changed Temp sensor but the problem never stopped ,i m not sure where the Idle control valve is on the car,,maybe i should replace that too.
its misfiring if i drive on a cold engine but once the temperature is high,it drives ok ,,,it can idle on its own but rough .....the car is find though except all i have mentioned
