My 2001 blazer service engine soon light is on and reads that all 6 of my cyl are misfiring...can anyone tell me where i should start??? I bought my blazer about 3 months ago and i know that the plugs and wires were replace 9 months ago as well as the intake manifold gaskets...i've read that the brand of spark plugs could pssibly be the problem...was also wondering if a new fuel filter and injectors could possible fix this???

 

Hi

If all 6 are misfiring it points to a common point on the ignition system. That being the Distributor. I would start there. I can see 1 plug or 1 wire being bad. If the voodoo is really against you maybe 2 but all 6???. That's the distributor or an outside chance the coil. Again in my humble opinion

Best of luck
Don
