Engine management light comes on and then the car will only crawl uphill - Daewoo Matiz. Only done about 50,000 miles and local mechanic can not find fault.

Question edited for clarity, 'Matiz' not 'Martiz'.

I have had no experience with Daewoo since they were not widely distributed in the US, but if the engine casting is the same then the newer engine should fit nicely. You will have to swap out some of the control circuits for the newer ignition system. I suggest spending some time around your local salvage yard comparing your model year to that of the engine donor to see what needs to be swapped. Take plenty of detailed pictures for reference when you (or your mechanic) is doing the work.

See if this helps. It's for the 1Liter -
Service Manual2006 Matiz 1 0L SOHC ENGINE MECHANICAL

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.

Your owners manual should have diagram of radiator and coolant reservoir. If not call your local Chevy or Daewoo dealer (Daewoo makes the Matiz for Chevy)

you mught go to dealer and avoid run arounds.....

check the bash plate under the gear box it may have been bent and is now banging on the gearbox.

Does your your alarm ligth stay on when switch car on? If it does then ther is a problem with your car alarm system.

Under your stearing rack is a white box. Take it to your local car alarm dealer to get new car ship and get new ship melted in your key.

sounds like an ECU fault ---dealer only
