Did the issue start after a particular service, software update, o r sensor replacement?

Sometimes sputtering begins after an ECU update, throttle body cleaning, o r sensor change. Was there any link between recent maintenance and the onset of the engine issue?

In some cases, sputtering started after ECU remapping, throttle body cleaning, o r sensor replacements like MAF o r O2 sensors. If the system isn’t recalibrated properly, it can cause incorrect fuel-air ratios, leading to hesitation. It’s important that such services are performed at authorized Changan service centers.
