MY BLAZER JUST GOT A NEW ENGINE LAST YEAR, AND HAS ABOUT 20,00 MILES ON IT. I KEEP GETTING A SES LIGHT, BUT THEN IT TURNS OFF AFTER ABOUT 20 MILES. I KNOW THIS MEANS THERE IS A MISFIRE IN THE 5TH CYLINDER, BUT A LITTLE UNSURE AS TO WHAT I SHOULD DO. I KNOW TO CHECK THE SPARK PLUGS AND WIRES, ANYTHING ELSE?[/quote:5de9b2f1ef]
Hello,
Well there won't be much to check for the plug wires cause all there is the plug boot. Your vehicle has the Coil Over which is that there is a coil that sets on top of each plug.
Do check the boot. A good way to check to see it there is a bad boot is to wait till gets dark unless you have a garage you can darken start the vehicle and look for sparks
Also check your wiring to the coil. Could also be a bad coil. When they replace the engine did they use a lot of the parts off your old engine?
