1st question - when was last tune up? Plugs, wires, cap, rotor, all fluids & filters including fuel filter. I'd start there and run a good fuel system cleaner through it. Another thing to watch for that Pontiacs are notorious for is timing chain & gears going bad. Right about 70k-90k you're in the "dark zone" and they give little or no warning. You might consider changing them out also.

2003 blazer p301 code ive changed coil plugs check engen still flashing when accelerating

The flashing light means the problem is serious enough to damage the catalytic converter.
The code means cylinder 1 is not producing power. So it could be fuel, compression, or ignition related.

Vibration on acceleration

Take the car to have the tires rotated and balanced. That should cure the problem unless the brake rotors are warped.

Transmission Vibration i think

it could be from slightly bent axles or bad suspension such as tie rod ends or ball joints but I would lean towards axles if only certain speeds.
