Question about 1999 Daewoo Nubira
The fault seems to be in the electrics of the ignition system. So it will be ideal to have the impulse to the coil checked. If the ignition system is faulty the fault you have explained can be a result.
The plugs, the HT wires can be alright as teh car works well when it runs But the HT coil can also be a suspect.
But I would prefer to suspect the Ignition pulse to the coil, if so checked for failure in the electronic unit for sure as this erratic condition is likely of a faulty semiconductor.

These kind of problems are tough to diagnose. I would start by getting it running and take it to Autozone and getting the diagnostics on it. It is free for them to test it for you. The computer in the car stores all of the errors that the car has had. So this will tell you where to start. I don't want to jump the gun, but it really sounds like the ECU is going bad. But again, it is free to take it there and without me being there and running some tests it is really hard to say.

Ask a local mechanic to check the crank sensor for you ,this is one of them jobs that could be a cheap repair but without the right knowledge you could change everything which costs a fortune and doesnt cure it ,these cars are quite simple and are based on a europeon opel (GM) so as it runs then doesnt its one of two things ,either spark or fuel and i suspect the spark but?? i dont have car in front of me to look at it you must have a local man that the neighbours recomend

You need to check for codes using a scanner and also check for faulty sensor data. If all this is ok then you need to check fuel pressure when its having a problem. Its all a guess until you eliminate options thru component testing. It sounds like your goingto have to have a shop look at this if you don't have the tools.

Hi! It's definitely a MAF (mass air flow) sensor problem. THe MAF has big contribution on engine performance specially on the idling and vacuum supply. If the MAF is faulty, stalling and hard starting can occur. Have the MAF repaced and you'll be good. Hope this helps and thank you for using FixYa!
