29 should be a good gap.
u can look up on hond atech how to check the code b4 u get there. 2 wire, blue plug, above passenger side kick panel. jump the 2 wires and count CEL flashes. Long blinks are the first number, short blinks are the 2nd number.

make sure u have correct amount of oil and coolant. no wierd idling issues. and extra money to pay for repairs if u miss or forget something. lmao!!!
