Your truck, car, or ATV will have alot of trouble starting. If so take it off and see what it looks like. If its black or brown its bad.
does anyone know where the sparkplugs are located on the engine on a 2003 Chevy trailblazer
don"t know.
That's a pretty good indication that the rings are bad I don't know how many miles are on it so that's a good place to start. hope this helps
Check for codes... It maybe a bad coilpack. Or bad sparkplugs.
Check your spark plug wires. They maybe bad.
Sparkplugs are almost universal, because of the way sparkplugs work and the way they are shaped the same, it means you should be able to use "standard" sparkplugs.
I had a problem just like that, I replaced sparkplugs and wires and my engine had a bad miss also; performed a compression test on all cylinders check out good ; found out sparkplugs was bad, got those NGK's sparkplugs ran better than ever.
There are six and i know the rear ones are very hard to get to
Bad sparkplugs. Timing is off. If no distubrator then bad coil pack. Fuel mixture may be off.
You can't harm the engine but you can fowl sparkplugs quite easily. More common on 2 stroke bikes.
possibly yes, with a bad o2 sensor you can have the wrong gas/air mixture making it harder for the sparkplugs to ignite the gas.
In theory, it could, but in all practicality, it would not. The four main causes of misfires are faulty sparkplugs, bad spark plug wires, bad fuel injectors or a loss of compression.
