Best Answer

It could possibly be an additive in the fuel. Some types of fuel injector cleaner can clean as well as possibly damage fuel injectors. It's also possible that debris from somewhere in the fuel lines is getting into them. It wouldn't hurt to change the fuel filter and check the fuel pressure to see if the fuel pump is operating correctly. Another possibility might be the electrical side of the system.

Your Daewoo lanos is making a knocking sound what do you do?

I would recommend taking it to a mechanic and have them listen to it. Everyone's definition of "knocking" is slightly different. Try not to drive it for too long; engine knocks can usually cause pretty severe damage to an engine.


How to check for bent valves on 2001 Daewoo Lanos?

compression check The Daewoo Lanos has an interference engine, if the timing belt failed, there is a strong possibility the pistons hit valves before the engine stopped completely. First perform a compression test, if the valves are bent they will not seal properly and the compression readings will be low. Keep in mind if the timing belt is broken or not installed correctly, this could cause cylinders to have low compression also. Inspect with a fiber optic borescope through the spark plug holes, look for impressions in the piston tops. The fiber optic borescope can help by giving an indication of the damage that may have occured without disassembly.


Does carbin bildup on fuel injectors cause backfire?

Normally you do not get carbon buildup on injectors. They can get gummed a little, or blocked, but that should not cause backfire. Check timing.


Will gas clean injectors in a diesel?

Gasoline will not dissolve the carbon deposits that clog the injectors but it will cause your engine to not start.


What would cause a 2000 Daewoo Lanos 1.6 to idle okay but no power and the engine roars as it chugs along when driving?

If you have a manual transmission, then it sounds like your clutch is slipping and needs to be replaced. If the RPM's of the engine are roaring and your car is barely moving, that would be my first assumption. Mechanic.
