I just bought a 95Z and would like to do a tune-up and full switch to synthetics.I was just wondering if I should change the O2`s (car has 185,000Km) but passed the emission test no problem.I also see this car
has plain old green coolant instead of the pink dexcool.I don`t think that
is a problem is it?So plugs and wires anything else?

 

I'd go ahead and change out the 02's with that many miles. Plugs and wires are also usual tune-up things to do. Also, change tranny and rear end fluid.
