i bought a 2010 mehran... the problem is that the engine is eating too much fuel and car does not pick up good. engine is also not sounding very smooth... the engine oil was very dirty when i bought it i changed the oil... car is driven 70000 but start to vibrate at low rpm does not give good acceleration... what could be the problem and whats the solution
Are you driving it on CNG as well?
not driving cng... but the last owner use it very roughly and driven it on cng also
Actually it is the matter related to the PETROL-AIR mixture setting. As the previous owner has driven this car well on CNG then your car is set on CNG-AIR mixture setting . You should go to a good mechanic for the re-setting of PETROL-AIR mixture setting. Then you will feel a big difference while driving. Secondly the science behind all this is when you drive the car on CNG then it require less AIR while on petrol it require more Air. So Air path to Air Filter should also be clear (without any rubber which is used for CNG). Lastly, the Advance/Retard Ignition timing settings will be readjusted for petrol.
thank u brother for help... this car is fitted with genuine cng so it should work on petrol & cng... aap ke suggestions try ke dekhta hoon. do u think that these problems are not related to ring pistons and any need for replacing spark plugs
Get it tuned by 3s dealer charges are 600rs. They may ask you to change plugs this and that don't listen to them get it tuned and replace the parts from open market.
thank u for helping
If your car gives visible Smoke then it would be the problem of ring/piston otherwise there is no such issue. You can contact a good mechanic and can get resolved the issue within 10 mins.
thank u very much
Sometimes dirty carburetor is also the culprit of smoke (KACHA DHUAN) , my mehran started giving white smoke but the culprit was just the carburetor , got the carby serviced and car was great again
OP share ur ride pics with us
Adjust air-petrol mixture and ignition timining.....clean carburetor if neccessary...
