Check for sticking valves also check cooling system and see if compression is leaking into it, just take of radiator cap crank engine over and see if any coolant spits out

Why can't I get power when driving.


Engine size??? total Mileage??? is it well maintained??? If it was "flooding out", you would smell gas...the newer vehicles seldom "flood out"., and if they do, there must be an ignition problem...not usually the key ignition, but the spark itself...the Daewoo's were never known for their "power", but a few had *****...how many miles are on it??? and what level of gas do you use??? low grade??? Medium??? High Octane??? a lot of things, can make a big difference...is you air filter clean???

Reverse lights not working


When you press the brake petal it activates a switch located under your dash. Just follow your brake petal up until you see something that compresses when you apply the brakes. It is possible that the switch is not lined up or needs to be replaced.

Try checking the snorkel tube between the air cleaner and the intake. Open the hood, and have a friend try to rev the engine, and watch the tube...my '92's was collapsing and starving the engine, couldn't get more than 3500-4000 rpm. Could also be a fuel pump problem like low pressure or bad line.
