LT1 acting weird
When Im driving around at say 40mph it tends to stay at higher rpms (3200 stall???) then when i let off it holds high rpms (like its engine breaking or something) for a second or two then suddenly and drastically drops below 900rpm or so only to shoot right back up to a normal above 1000rpm. At slow speeds such as coming to a stop or slowly reversing the car sometimes stalls. The idle can also get pretty bouncy from time to time at low speeds. The car has a pcmforless tune and the only code it throws is for the evap because they forgot to tune that out. Any ideas?
