A common rule of thumb for spark plugs in the Chevy Colorado is to change them every 5 years or at 150,000 miles. Over time, just like any other part, spark plugs can wear out and become ineffective. Since they play a critical role in igniting the spark that starts your engine, it's crucial to replace them before they completely malfunction. If you observe symptoms such as engine misfires, sluggish acceleration, decreased fuel efficiency, or rough idling, it may indicate that the spark plugs are starting to fail. It's important not to ignore these signs and to promptly seek a mechanic's assistance to avoid any further issues while driving.
My pickup is a 2015 Chevy Colorado, and the check engine light is indicating that one of my spark plugs needs to be replaced. Although the truck only has 50,000 miles on it, it's five years old. Should I go ahead and replace the spark plugs?
It's best to change the spark plugs every five years or 150,000 miles, depending on which one occurs first.
