I went to auto zone to get my check engine light checked. The code reader said:

Cylinder misfire on cylinder 1 and 4
Random misfire

Does anyone know what misfire means? what kind of a problem iam looking at and how much would it cost?

Thanks

Read my diagnosis and description of misfiring here:-

could be as cheap as a sparkplug (a couple of bucks), or expensive as a new harness (US$700). I think you need to look at the leads for cylinder 1 and 4. follow them from the plug to the coil. Check the joints are connected properly. If they share the same coil, replace it.

it seems like u have one prablem after anather wit your 6er is this the saim delema from before with the spark plugs that u had the shop replace for u sounds like it.
Actually, I will be giving the car to the dealer for a complete fixup. There they will correct the engine light, ball joints, suspension, interior lighting, heater blower and some other stuff.

Here goes my holiday bonus $$$$
