Diagnosing a cylinder miss

Discover the common causes and symptoms of a cylinder miss, including burned valves, piston issues, and valve sticking. Learn about the importance of compression, ignition, fuel mixture, and how factors like vacuum leaks and manifold restrictions impact engine condition. We explore solutions for both electronic and standard ignition systems, the role of EGR (Exhaust Gas Recirculation), and fuel injection problems. With proper diagnosis and adjustments, ensure your engine performs optimally. Get insights on balance tests and tools needed for effective troubleshooting.
