Shopping of leaks

Hello good there is some way to check if my car is leaks in the admission, escape or valve collector or valve something that is not very complicated. My car is a 2000i gasoline in 1995. Thank you

Of course, the easiest way is to take out the hose that enters the mouth of the admission and put the hand if the vehicle continues to walk, you have air leaks, but it would be important that you told us what your model brand is model and what is your problem to help you

If my car is a 2000 Renault Laguna.

If that is the case, see that cylinder is failing, identify it by taking the cables one by one, to see if the vehicle fails in some the vehicle will be the same or fails less and that is the one that has the problem, if it is not with cables and it is with independent coil Fuel, and then we see what we do, taking out the spark plugs is a good parameter since when looking at their status you can identify the failures. Good luck and tell us to continue giandote.

If I have checked the spark plugs, taking out the cables and everything is going well. The spark plug wires, distributor, spark plugs and coolant sensor I have changed it new. That can be thanks
