I have no idea what's wrong with it. I haven't been able to find a vac leak. did have an exhaust leak that is fixed now. I'm on 42 lb injectors and a northstar tb/maf. I'm planning a swap to 130 lb springs in the next couple months, so we will see what difference that makes. doing a double roller timing chain and a bigger harmonic balancer in the next month.
