Can anyone out there send me a step by step on how I can tune my 99 z28 camaro?

Thanks

Change the plugs
Scan with OBDII diagnostic tool. Read codes. Fix issues. Delete codes.
Sometimes it is good to reflash the PCM with a fresh tune.

I would also change fuel filter, PCV valve, clean MAF sensor wires.

 

Thanks for the tips. But how do you get to the last 2 plugs in the back?
Also do you know where I can get a step by step in picture form?

 

It probably wouldn't hurt to run a can of Seafoam or it's equivalent through the intake and/or gas tank before you put the plugs and stuff in. The only thing I'm not sure about is if will affect your O2's or not. There's some debate over whether or not it causes them harm.

 

New plugs-New plug wires-New fuel filter-Clean or change air filter-Change oil and filter
I put some fuel system cleaner in gas tank. On the last two plugs in the back I changed them from under the car there a lot easier to get to from the bottom. I also had some swivel socket extension that work great.

 

I thought it was rather easy to do the plugs on my '98 for the motor being halfway under the cowl. 2-2.5 hours at midnight for me.

Ratchet, 5/8" spark plug socket with 3/4" hex on back end, 3/4" wrench, 1 1/2" 3/8 extension, 3" 3/8 extension.

The #8 plug is a lot easier once you remove the coil packs on that side.

Pull the AIR tubes before you start, makes a lot more room in there for your hands.
