As I have posted before I still have a vacume problem. When I step on the gas and come to a complete stop my rpm gauge drops to 500 rpm and then goes up quickly to about 1200rpm and slowly drops to 700-500 rpm. But when i slam the gas and make v-tech kick in and rev up to 8200 i let go of the peddle and my rpm gauge drops to 500 rpm and then 1200 rpm it does this about 3 times until it slowly drops to about 500- 700 rpm. I have a jdm b16 in my si eg.help.please.

 

check your tps sensor it might need to be adjusted
