salam!
i am facing a problem since JULY
i own CULTUS VXR 2006 NOV
after 500 Kms of tuning of CNG specially
car's performance goes to lower grades
it starts missing
and with full race padle it hardly crosses 2500 RPM
this is without AC
with AC its hillarious
main problem yai hay k
mechanic k pas jao woh 2 sec mai theek kr daita hai
but kuch 100 kms k baad ee problem wapis aa jati hai
have shown to many athorised workshops
and when i took it to the dealer from whome i bought it
he said! we hv to dismentle the CNG cylender, after that we can diagnose the main issue
so kindly suggest me with total care
