Why does my 94 9c1 caprice feel like its going to stall when it downshifts into 1st gear when not warmed up?

Your 1994 Caprice's stalling sensation when downshifting into 1st gear while cold could be due to a few factors. The engine may not be reaching optimal operating temperature, causing the idle speed to drop and leading to insufficient power when engaging the lower gear. Additionally, issues with the throttle position sensor, idle air control valve, or even Transmission Fluid levels could contribute to this behavior. It's advisable to inspect these components and ensure the engine is properly warmed up before driving.
