Honda City 06 CNG Mileage and some other problems

[waqasmasood1]

Hi all, recently i got city 06, manual

i am facing some issues and need your help

giving a poor mieage on CNG, abt 110-115km on motrway with 55k cylinder and even poor in city, mechanic told to get the cylinder cleaned (CNG tuning) but i dont think that would make a good difference. petrol average is good enough.14km/l approximately

2ndly rpm starts droping once its runs more than 100kms on CNG

3rdly starts bubling/vibration at 130km/hr plus speed on petrol and CNG both.

engine seems quite okay,

looking forward for decent suggestions, mechanic hazrat to frmate hei, cng utarwa do

regards,
waqas

for bubbling thats the alingment issue.....and get ur cng tuned....find a good mechanic i did my friends citys cng testing tuning from tipu road.....dont remember the shop name but it is opposite to fugi tower next to the car wash...not the pso one....

how much does a cylinder top up cost?
is there emulator and advancer installed?are they functional?

for wobbling get wheel balancing(not alignment) done

^ no advancer?
how r u even running this thing on cng without advancer. get an advancer ASAP caz this car has DIS & u cant tune the ignition timing manually for cng. just install advancer & everything will be OK
