What causes rough idle in a petrol car?
Rough idle on petrol cars has three main causes: throttle body carbon deposits (most common, cleanable for ₹2,500), idle air control valve blockage (same cleaning), or faulty O2/MAF sensor sending wrong mixture signal. GarageNation performs a multi-point idle quality test — idle speed, long-term fuel trim, and cylinder balance — to pinpoint the exact cause before any cleaning.
How often should the throttle body be cleaned?
Throttle body cleaning is recommended every 40,000–60,000 km or when rough idle symptoms appear. GarageNation includes a throttle body inspection with every major service. Cars using port injection (Maruti K-series, Honda i-VTEC) need cleaning more often than direct-injection cars because intake valves see no fuel wash.
