Stick to the recomended spark plugs, thats just me oem
trans, my unc uses Royal Purple trans fluid in his race car. no complants, runs good. timing chian or belt, spark plug wires, top off radiator, power brake fluid, Power steering fluid, check all the levels and check the tire pressure. try running 93 oct and octain booster, Zmax or Lucas gas treatment, it may need a fuel injector cleaning try the Zmax or lucas gas treatment and 93 octain first.
Have a fun and safe trip
