You just filled up your tank and now that dreaded check engine light is glowing on your dashboard. What gives? This happens more often than you'd think, and it's usually not a major crisis. The most common culprit is a loose or damaged gas cap. When you don't tighten it properly after refueling, your car's evaporative emission system detects a leak and triggers the warning light. Sometimes the cap itself has a worn seal that won't hold pressure anymore. Before you panic, try tightening the cap until it clicks three times. If the light stays on after a day or two of driving, it's time to visit an Auto Repair Shop Houston to scan the codes. Could also be a faulty purge valve or even a cracked filler neck, and an Auto Mechanic Houston can diagnose the real issue quickly.
