Help me I'm new and I have a problem with My Car

Hello, hello to everyone, I am new, my problem is Gonzalo, my problem is this I have a 19 Diesel rd e [white with 4 doors and 4 wheels hehe] well the problem is that when the rpm lower the engine the engine stops and devote to accelerate it or stop. Well we thought it was air or some relay but we do not save it we want to be well if someone save something about this or from a manual where the answer comes out, I would thank you very much.

My run is
Add me

Good morning,

give me more data, motor model for example (I think it's the same as Clio) to see if I can help

you

Well I am a mechanic I do not have many data,

it is a renault 19 re d the engine is Diesel, it has the engine of a clio 98 is a tank holds a lot but here it is not investigated. They have been taken out and the owner did not save if you disappoint


a second answer if you can thank you if you want to send you some photos of the car and the brand but it is not so much it is a bosh Diesel bomb and it has the incandestent Diesel spark plugs

Good morning, if you are a mechanic as you say
what I would be serious,
1st I would look at the distribution strap that is healthy, I mean that you check that it is its marks,
2nd if it is in its marks, I would take the injectors even the incondent spark plugs that is simpler and check if the engine has compression "turning the engine through the firp drive in the direction of the crankshaft in the direction of turn Praying I have tried to start it,
if I did not have a compression, you would have no choice but to take out the "" "butt" engine to see the problem
now I have a clio at home that happened to him the same thing with the alternator's strap and split the camshaft, but neither touched valves, nor cylinder head. No pistons questions of luck
is what I would make clear, there will be colleagues in the forum that will have another opinion

greetings

You are right thing is best to review everything Gescan says, it may also be that the bomb is out of point, so Readí does not remain ..
You have to review many things everything that says.
especially the distribution strap.
There you warn what happens .. greetings
