How often should the Corolla fuel injectors be cleaned?
2 Answers
This car's fuel injectors do not require special cleaning. Below is an introduction to the Corolla: 1. Overview: The Corolla, formerly translated as "Corolla Flower," is a brand under Toyota Motors. The Corolla is equipped with Michelin 215/45-R17 tires, TRD-Sportivo high-performance shock absorbers, TRD-TF4 17-inch sport rims, reinforced clutches, and high-performance brake pads to ensure excellent sporty performance. 2. Space: The Corolla has been lengthened in terms of body size, with the wheelbase reaching 2700mm after the extension. In terms of seating space, a 177cm-tall tester adjusted the front seat to the lowest position, leaving a fist's width of headroom. When moving to the rear seat, the headroom was two fingers' width, and the legroom was one fist and three fingers' width. The floor bulge in the middle of the Corolla's rear seat is minimal.
As a long-time Corolla owner, I find the frequency of fuel injector cleaning quite crucial. It affects fuel atomization and engine performance. Neglecting cleaning can lead to poor fuel injection, soaring fuel consumption, insufficient power, and even engine shaking during startup. Specifically for the Corolla, Toyota doesn't mandate a fixed cleaning interval, but based on experience, I recommend cleaning every 20,000 km or 1.5 years. Considering urban traffic congestion where frequent idling causes carbon buildup, more frequent cleaning is advised; those who drive more on highways can extend it to 30,000 km. Cleaning methods include physical disassembly or using additives, with professional shop service being more reliable. Preventive maintenance can avoid engine clogging, saving money and ensuring safety.
