Cold start problems

I have a 306XND and three months ago starts like three cylinders and with an amount of smoke that shakes, it looks like a biker burning wheel. I changed the heaters and hardly improved ..
Someone can guide me if I have to clean the injectors or what to do not to give more blind sticks, thanks in advance!
PD: When he gets a little he keeps the slowdown and does not give me more problems, but it is as if he started drowned in cold

Hello Trujo, you may have some "grabbed" injector, with the engine torn, see loosening the racord of the injector (one by one) to see if it fails (you will not notice variation when you loosen the pipe) this will be the one that is evil, in the return sleeve, you will see that it throws more than the rest, alish "grabbed" in cold, from there when it already warms something better.
On the other hand, check the pump adjustment values ​​(on this page is the Peugeot Manual) you will see if the thermostatic probe that goes with cable from the water box to the pump is damaged (you can regulate it with screw). Greetings!!!


*Cleaning the injectors, it is not simple without means, nor the tarado of these.
