For resolving patakha problem in baleno 99
first check air filter condition and box tightness
then spark plug gap , replace spark plugs if driven more than 15000 km
Finally if problem still persists, replace plug wires
Last option is to check coils(not costly for baleno 99)
Patakha and missing problem in 2nd gear espacially is due to lack of current
Bad spark plug wires give problem mostly in CNG only
Bad Coil give problem both in CNG and petrol
I'm having a baleeno 99 for last 7 months
My baleno had similar performance issues in 2nd gear
After changing spark plugs and gaping patakha problem arose
Finally I figured out that main culprit is bad spark leads/wires
I simply changed wires and all performance problems resolved
Hope it will help other baleno owners
