What Are Symptoms Of Dirty Injectors?
One of the most noticeable symptoms is roughness at idle or missing. Another symptom is poor fuel economy. One of the worst problems of an injector that under-performs is that it causes a lean mixture at higher RPM and high engine load. Most performance engines had compression ratios upwards of 11 to 1 and lean mixtures can cause detonation and burnt valves. Faulty injectors, especially in turbocharged and supercharged cars can burn holes in the tops of pistons, and even more catastrophic damage. Many cars have knock sensors that prevent detonation, but this robs you of horsepower and econmy.
