Engine does not accelerate

Hello everyone, I am working on a Tucson Crdi Motor 2.0 2005. When leaving it works as a drowned and does not accelerate. After a couple of minutes it just accelerates but only reaches about 2900 rpm. The scanner does not throw any fault code.
If someone has a contribution, I will appreciate it.

Hello friend, it offers more details of the fault and surely someone can give you a successful answer. A friend had a similar fault but the car did not give more than 3000 rpm and drowned, it only remained below that value, they took him to the scanner and did not throw error ... but !!! If there was an error, the ECU, engine switchboard or computer, as they call it according to the location, it was bad, since it realized when tested with a borrow. He bought a new and voila.
It may not be your case, since there may be many basic factors associated with this fault such as: dirty injectors, problems with spark plug cables, dirty fuel filter (it happened to me once) etc.

Greetings, hopefully you can solve soon!

You should start with basic points: Verify fuel pump (fundamental) injectors a cleaning by ultrasound is recommended. If the vehicle regulates well and only in certain laps the lodge fails is that the wiring and spark plugs should not be although nothing should be ruled out. On the other hand, some sensor disconnected or without working. For example, absolute pressure measurement usually gives this type of effects is normally on some sector of admission multiple. Pñor Another Scanner Ladolos are not magical and only serve to deliver not always effective data for repair. What you should have is a sensor emulator with which you could check if any of them is the problem. In turn, it is always advisable to have an oscilloscope to measure some basic points. It would be good to comment more accurately the defect. It could also be a mechanical issue and not the injection. For example, a bad position of the cambaces with respect to the crankshaft. An inadequate valve lus. In this case, use hydraulic bumps which could be defective. In other words, a unnamed problem that it does not have to do with the injection. I still lean to the fuel pump or its internal and external filters or the alleged regulatory valve. of the pump. Greetings and luck
