RPM on CNG and Petrol keeps on flutuating all the time... (for petrol it is above 1400 and for CNG it is from 500 to 1100) One expert Mech told to get the throttle body repaired...but still no change..
"Get the trhottle body sensor checked. I had the same problem and my mechanic replaced the throttle body sensor and the RPM became stable".
Car gives constant vibration on CNG...i have shown it too many Cng and electronic Experts in Pindi...
"Check if the tappets are adjusted properly".
all they check is the plugs and the plug coils....they think there is some current leakage... But nobody has been able to solve the problem..
"Might be some issue with the coils. If you can get hold of another lancer, change the coils with yours and check if it makes a difference before you go buying a new set for your car."
Cng Mileage is quite heavy .... (75 to 80 km in 350 to 370 Rs cylinder in city) I know it 1.6 Litre..But I have Heard that civics n se saloons do better than this...(may be around 100 km per cylinder)..lancer has a relativiely light engine (lancer 1.6=77 Kw , Civic exi= 81 kw ,Civic vti=96 Kw)ref.... My bros 2004 exi(prosmatec) does 110 km within city...
" Once you have the above mentioned problems solved, you will have a better miliage on CNG. Mine does 120km in the city with AC" and its a 1.6 as well".
Egine gives white smoke...Mechs told me that if the engine is weak.then the engine will evaporate quickly....but I do chk it regularly but its level is very slightly lowered (like every cng veh) have driven 4000 kms so far (using ZIC cng engine oil)
"White somke is a sign of weak rings... get that checked from a good mechanic".
GuYS Help me and tell me whether these problems are there in all lancers M/T...
