Why would a Daewoo Matiz lose engine power?

what is the convertorsI would start by checking the convertors

Could be any number of things. Could be:-

1. Blockage in your fuel filter

2. Blockage in your cat convertor

3. Blockage in your fuel pipe

4. Faulty Map/Oxygen sensor

5. Dirty or faulty injector

6. Exhaust Blockage

7. Low Voltage i.e. battery/HT lead/Dissy Cap/Rotar Arm/Sparks

(you may be running on only 2 cyclinders!)

and this list is by no means exhausted...

My advice is to cough up £60/£70 and go to a dealer to get a read out, but before that do number 1 & 7 as they are cheap to do, any probably needs changing anyway!

My 2001 Matiz recently had some problems. Initially, when trying to start the motor, it wouldn't start and there was no noise at all indicating a problem with the starter motor. After clutch starting it and 5km down the road, it began to lose power finally losing all power at the traffic lights. After getting it towed, I was told that it was a problem with the computer and that the starter motor, battery and alternator were perfect and there was no blockage in the fuel pipe.

A Holden representative had to visit the mechanic with his piece of equipment that interprets the error code that was coming from the computer and there was found to be a problem with the cambus part in computer. Additionally, there was found to be water in the distributor (how it got here I don't know how). All up to fix this issue was $140 AUSTRALIAN DOLLAR. $100.00 was for the hour the Holden rep spent at the mechanics performing the diagnostic system scan. The $40 AUD was the mechanic's work fixing the distributor (apparently there was a distributor pipe that was facing upwards allowing water to enter).

I hope this helps,
