If its a higher mileage engine it sounds as if the pistons compression rings are worn out therefore causing the engine to stumble. first check the catalytic converter it could be clogged or old, this is most likely but if its high mileage then do a compression test on each cylinder. 90 lbs psi is ok but couldn't hurt to be better

SOURCE: fuel pump on Daewoo Lanos 1.3

Hi

If my memory serves me right the Lanos has an immersed pump, and therefor you need to be looking either under the rear seats or in the luggage compartment for a round metal or plastic cover which when removed will uncover the top of the pump and fuel sender unit.

It is probably held in place by a large plastic or metal ring which either has to be unscrewed or just turned slightly to disengage the securing lugs.

PLEASE DISCONNECT THE BATTERY NEGATIVE TERMINAL BEFORE MESSING WITH THE PUMP OR YOU MAY HAVE AN EARLY FIREWORKS DISPLAY!!!

Just as a matter of interest, I assume when you say FLUIDS you actually mean FLOODS, in which case, the problem isn't the pump.

If the car doesn't start, or struggles to do so, and there is a smell of fuel or the plugs are getting wet, then the problem is more likely to be a lack of spark than anything else.

There are other scenarios, such as a faulty coolant sensor (cold engine), a faulty O2 sensor (hot engine), a faulty throttle position sensor (hot or cold engine), and a few others I could mention.

If you require any further help, just click ASK ME under my strange white round faced picture (which my MRS reckons looks just like me!!) and I shall be more than happy to assist you further.

Regards

SOURCE: Losing Power

2.5L is really lacking on power. what had to do is route the air inlet tube for the filter box to the front of the truck right beside the radiator that what it pushes air into the motor and have more power. now the truck gets better gas mileage and has more power to get over the hill. only thing is the filter gets dirty more often and gas mileage goes down in the winter cause the cold air makes it use more gas

SOURCE: car loses power when going

The first thing you need to check is fuel pressure. If you don't have a fuel pressure gauge you can buy one from a tool supplier, but the gauge may costs more than the diagnosis from a shop.
Another thing you may want to check is you catalytic convertor to make sure that it is not plugged.

SOURCE: losing power up one particular long hill

It sounds like a tranny problem. Without more info kinda hard to diagnose. The simplist thing to check is tranny fluid. If its low, going up a hill will pull fluid out of the torque converter. It could be the converter itself. It could possibly a fuel problem, but unlikely. Hope this helps. John...

1998 dawoo lanos.when the engine is hot. Car loses power up hill only


Old spark plugs loose power, under a load the increased pressure blows out a weak spark before the fuel is ignited.

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 bought a 1997 Dawoo Esspero and the motor is very noisy.can any one tell me wot the problem could be.


the engine is loud as in the exhaust? maybe you are hearing lifters clatter? louder or more noticeable at idle or as you climb a hill? take a look at the oil level on the dipstick. if you have a low oil level and some engine noises then the noises go away when you add the correct amount of oil that would be normal. hope that helps
