Check fuel filter and check fuel for water or contaminents
then check fuel pressure with gauge also while driving
may have pin hole in leads - spray water with salt solution over HT leads while engine running and then rev to see or here spark jump(missfire)
recheck spark plugs - did you crack any on installation/removal/installation?
what are the codes and description if stored?
what is engine live data parameters like do they look normal (right specs for range/operation)?

2000 Dae Woo Lanos 1.5L keep getting a DTC Code


you will have to check the fuel injector for operation. then check for a vacuum leak where the intake mounts by cylinder 4, could also be a compression problem for that cylinder. an 02 sensor won`t cause a single cylinder misfire or fuel filter.

Surging/loss of power up steep hills in Daewoo Lanos 2001


This sounds like you may correct in saying a misfire. this sounds like a bad coil that looses power under a load. Is check engine light on?
If the light is on or not go to an auto parts store like auto zone.At auto zone they will scan the computer free of charge and give you a print out of any codes. the computer will store code or codes when it detects a problem. A bad coil will make it store a code or should.
see if there are any misfire codes, this code will help pin point the bad coil. if there are codes write me back and give me the code. I think this car has coil over plug ignition system. this just means instead of sparkplug wires the coil sits right on the top of the plug.
Also replace spark plugs if it has been a while since they have been replaced. check air filter too. a matter of fact if you have over 70,000 miles on car tune it up. plugs,furl filter if it has one, air filter and pvc valve and clean throtle body.
Okay, just checked it out, this car if a 1.6 engine then does have a coil but not on spark plug, rather coil with sparkplug wires going to plugs. try replacing spark plug wires and plugs first and if problem remains then replace the coil. let me know the results. good day

I have a 2000 Daewoo Lanos with a check engine light code of P0240 can you assist me with this issue so I can pass smog


that's the o2 sensor code. it should say catalyst efficiency. you either need to replace one of your o2 sensors ($52 at autozone), or it could be your catalytic converter.

2001 daewoo lanos check engine light


oil is non conductive so I doubt that's the problem, but the oil leak should be fixed to reduce problems down the road.
as for the misfire could be a couple things, fouled plug(s), a plug wire(s) that has cracks, or even valves that are not seating which i doubt from your explanation.
I would change your plugs and wires first, and fix oil leak. if this does not fix the issue there are other things going on.

Car running lumpy, reduced power


Is the garage you took it to a daewoo dealership? If not then try one; they should be able to run a diagnostic. If so, take to a different one.

I would think it is the o2 sensor. If you disconnected it then it sounds like you have the knowledge to replace one. When mine went bad the car didn't stall.
