run fault codes first .Check for faulty o2 sensors and check the air filter is clean. Check fuel pressure in the rail. check for blocked exhaust system (cat converter) check for correct tyre pressures and check the load carried and the speed being driven at . Check that the od is operational and that the motor is not over reving at speed this car in proper operating mode should be around 6ltrs per 100 klm's travelled
have the fault codes read to determine if any sensors are out of parameters from the engine rebuild. If you did not get a rebore and you used existing pistons the smoke may be from excessive ring clearance and worn ring grooves in the pistons . I am not a believer in wearing in as all wear only gets worse (not better) but in this case may be some normal use will allow the rings to reseal in the worn ring grooves over time
Do a code scanning and make sure that there are no DTC codes stored. Check for common faults that may result in high emission:
Check air intake and air filter, check also the sensors in the air intake (MAF and IAT). A problem in the air intake may result in rich mixture and in high emission. Check that distribution is OK, replace sparks plugs. Make sure that oil has been bled and replaced. Check that there is no vacuum leak. A vacuum leak may result in lean mixture and occasionally cause misfire. Double check the O2 sensors, they determine the air/fuel ratio in the mixture being injected. Do an injectors cleanup. Do a compression test. Your engine is 15 years old. Depending on mileage and on maintenance history the piston rings or head gasket may start giving some troubles. Check the color of the smoke from exhaust and check the result of the failed emission test. That may help understanding what is wrong with the car.
Hi, Few things to check here, first i would check the Lambda sensor as this monitors the air fuel mixture and stops the car running too lean or too rich. The most likely option is that the catalytic converter may be at fault the element inside may have broken up over time and therefore is unable to breakdown the exhaust emission into a cleaner release of exhaust fumes resulting in emissions failure. At the very worst you may have worn piston oil rings that would also produce excessive smoke emissions from the exhaust.
i have a Daewoo Matiz 2000. It doesn't have Power Steering although other models of Matiz came with Power steering. I want to know if a Power steering can be installed on my Matiz. If so, whom can I contact.
