Awesome, with all the information you posted, it's hard to know where to begin.

Telling us it "runs like **** n ****" is so descriptive.

OK, the first thing that needs to be addressed is: what CELs are you getting? Answer that, and we'll go from there.

 

iight its running with a obd0 pr4 ecu codes are 5 blinks and a semi long 1blink its all that is giving me

 

5 blinks is Manifold Absolute Pressure: check the map sensor and circuit. A semi long 1 blink is Intake Air Temperature Sensor: Check sensor mounted on intake drivers side check for circuit.
