hey daniel lol thanks for the comments everyone, well, i don't hear no air leaks if thats what its suppose to sound like, my friend thought it was either an air leak or petrol, he checked the hoses though didn't find any leaks, and then he thought it was the petrol, i do recall walking behind the car after i've turned it off and it did smell funny. with the throttle body, i think it should still be good, i am not sure how to check this, and i meant 100~800rpm it feels like its trying to bog out. i've always been running 98, i've been uses vortex since i bought the car, but decide to try bp ultimate for the last two weeks, idle started playing up on the second week of bp ultimate
