A CNG converted vehicle that vibrates and loses power during acceleration usually points to one of a handful of known root causes. Most can be resolved by component replacement and professional re-calibration.
Common Root Causes
Weak ignition / worn spark plugs
Dirty gas filter & regulator pressure drift
Improper gas ECU calibration & air-fuel ratio
Blocked injector rail or air intake issues
Most power and vibration issues can be fixed by component replacement and professional re-calibration.
High-quality sequential injection kits deliver stable performance for trucks & passenger vehicles.
FAQ
