Ok i decided to get bosch platnium 2 sparkplugs. I know bad decision but i thought might as well give them a try since the store didnt carry ngk. So i put thes plugs in and now when if i floor the gas the engine just stops. No power at all for like 3 sec then revs like normal. It seems to get stuck and do this around 3500 rpm. but after a couple times of flooring it, and having this problem it goes away? Are you supposed to gap the bosch platnium 2 if so how?
