My 9 blazer has a miss and no check engine light on
I have a 98 chevy blazer with a 4.3 v6 it has new tune up parts and still has a miss and no
check engine light on. New plugs, wires , cap and rotor
Compression test needs to be done.
Hi friends, first check to see if the plug wires are arcing. Remove boot from plug. Look inside. See signs of arcing? This was a problem almost right away, and remains so today. Perhaps it's injectors, but GM had/has problem with factory wires, on the 4.3. my own had #4 wire arcing, doing same thing. Replaced wire, runs fine again. And, my wires were all new Delco Replacements. Best to replace with aftermarket silicone wires. Best wishes. Mike
