okay guys first off im new to the forum and i own a 2000 Chevy Blazer LS 4x4 ZR2 with the 4.3L Vortec Motor.

Now my first question is, with these motors, what do i need for a complete tune-up? I know how to do tuneups but the last tune up i did was on an old ford V8 and its a completley different generation of motors. Also what is a good website to get the best quality ignition parts. To me it does not matter how much money i spend for the tune up since i want to get the most out of the motor and id like to use performance parts.

thanks
Bill

 

Plugs, wires, cap, & rotor. I had good luck with the Napa Echlin brand of cap/rotor & their Belden Premium wires. For plugs, go with the AC Delco Double Platinum or Premium Iridium plugs.

 

I would also change the fuel filter, if it's been on there more than 30k miles.

 

how hard is it to do a fuel filter on these truck. my f150 was a PITA to do because of a previous owner and all. ended up cutting the original fitting off.
