My 2000 LS1 TA is running a bit off ever since my TR224 cam install. I am having problems when the AC is on, when I decelerate the car idle likes to dip below 500 RPMs and sometimes it stalls. Also during everyday driving when I decelrate to below 5-6 MPH or engage the clutch to downshift at lower speeds the car dips to around 500 RPMs and comes back up to 900 where idle is set. Car was tuned with LS1edit and he can't figure out what is wrong. Leak was first concern but manifold was replaced and resealed and problem still occurs. Anyone near Philly who can help?
