Daewo I await 2.0 year 93 monopunto.

I have my I wait with problems, I do not keep the slowdown since I arrive at 950rpm and it falls (stops and does not maintain) I have to keep it at 1200rpm which consumes me outstanding fuel separately.
Oh anyone who helps me? .....

Hello, good afternoon, your slowdown problem can be caused by the following: the IAC valve, the MAP, SERVO CANDERA CANDERA when the engine does not work in idle even the open EGR valve. And the theme of the taquies can be these, the oil is cared for the engine works with pure 10W40 as a maximum you can already make a 15W40 you can also look at the oil light if it blinks to be made you will have to check the oil pump or take the pressure to the pump better is faster I hope that my comment friend for you to solve so that you solve your problem.

Thank you but the engine according to the catalog and the same engine that the oil that must be used must be 20W50, is that or should I use 10W40?

Hello good afternoon, that engine works better with 10W40 oil or also 15W40 at least we have put that type of oil and work very well without any noise that is the recommended oil Usal it with confidence, of course that if everything depends on the mileage that you have your engine to use that oil and if otherwise the engine hits the engine with the 15W40 you will have to intervene your good engine good friend you try it and tell me.
