ok so this is for a friend of mine he recently got a crx with a built ls vtec in it and he changed the spark plugs on his car and for some reason it started to sputter, he gapped them to the specs of a gsr and for some wierd reason the old owner ran different spark plugs on like each cylinder, 2 top of the line and 1 cheapy and one 1 decent spark plug so now he got normal NGKs and its sputtering could it be he needs higher end spark plugs or is it the gaping or somehting need help
he also says sometimes the main relay starts to click while the car is on?
