Barring any mechanical issues you most likely have a failed injector.

97 chevy blazer rough idling problem? help?


It is hardly ever the spark plug or only the spark plug - generally for some reason there is a weak or lost spark and the reason must be found and rectified by carefully checking and then replacing any components found to be edfective - plug wires, coil, distributor cap, rotor (if fitted), wiring, connections and could conceivably even be the ECU. Perhaps the misfire is due to injector trouble...

Sometimes a fault with persist even after it has been "cured" until the fault code is erased with diagnostic equipment.

Any chance you get take that in to get the codes read. That is important and step one of the process. This will tell you the problem. If you are getting spark at the plug then more then likely you are having fuel problems.

How to install cap and rotor on a 2000 chevy blazer 4.3ltre v-6


Disconnect the wires and take pictures with cell phone for reference to ensure you don't cross them when reinstalling the new distributor cap. Remove the two torque screws in the distributor cap and remove the distributor cap to access the rotor. Remove the rotor by lifting straight up and inspect the distributor for any condensation and corrosion. Clean the breather screen at the bottom of the distributor before installing the new rotor which just slides back in place. Install the new distributor cap and tighten the new torque screws, make sure you do not over torque the screws since the distributor housing is plastic and prone to stripping. Reattach the spark plug wires and start the engine and idle for 5 min and go for a test drive. Good luck and you may want to also buy spark plug boot lubricant to ensure the spark plug wires are fully installed when placed back on the new distributor cap and recheck connections after test drive. Keep me posted, be glad to know your blazer is running 100% and please rate.
