First of all I am new to this forum and I wish to say HI to everyone here!

I have a Ford Escort Zetec 1.8 16v 1998, lately I have spend some money on it changing parts like timing belt, clutch etc.

Now I have another problem, when the car is cold it doesn't rev smoothly, obviously it doesn't run smoothly.

I am thinking that may be a lambda sensor..

Any suggestions??

Thanks in advance
