My 2001 Chevy Blazer 4.3 L Vortec V-6 problem I have a 2001 Chevy Blazer LT with a 4.3 liter Vortec V-6 and it starts and drives , but it doesn't have any power when I go to accelerate. The codes that come up are PO102 and PO341. I just installed a brand new distributor, cap, rotor and plugs. SOLVED: I have a 2001 chevy blazer 4.3 vortec engine and Feb 12, 20172001 Chevy Blazer (4dr / 4WD / 4.3 Vortec) with Code (P0300B) P0300 is a Random Misfire code. Try cleaning the Mass Air flow sensor with a electronics cleaner gently dropped on it and let dry(NO COMPRESSED AIR) before plugging back in and using vehicle. there may be a video of this online elsewhere.
