well the bronco has been acting up again...
its a 1993 ford bronco 351w efi automatic 4x4 xlt
The check engine light comes on, it shifts real hard and fills like its being choked, real low idle and it about or does die.
went to auto zone to pull codes and i got:

112. act/iat sensor circuit below min. volt.
117. ECT circuit sensor below min. volt.
122. TP sensor below min. volt.
126. MAP/BARO sensor higher than expected
327. EGR circuit above min. volt.
513. internal volt. fault
553. secondary air injection diverter circuit fault
552. secondary air injection bypass circuit fault
564. fan control circuit fault
556. fuel pump relay primary circuit fault
558. EGR (EVR) circuit fault
631. transmission control indicator lamp circuit fault during KOEO test
622. shift solenoid no. 2 circuit fault
638. 290 deg. F indicated by TOT sensor, or sensor circuit below minimum volt. circuit shortened
654. MLP sensor not indicating PARK during KOEO test

and there was more but the guy at auto zone was like its probably one thing causing all of the codes so he didn't get the rest.

last time it acted up similar to this i just changed the fuel pump, fuel filter, and PCV valve. It seemed to run great for about a month then it acted up again
your help would be greatly appreciated thanks

 

I think the gent at Autozone was pretty close to what was happening.
Whenever we get a load of codes like this there is usually a poor ground connection for the system.
I would suggest that you check every ground connection you can find and see especially the ones on the engine. While you are doing this you might as well check all the hot side supply connections too. Checking them means loosening them and retightening them especially if you see any rust or corrosion. Just looking at them does nothing. The components operate at very low voltages and the slightest resistance can affect the signals. Let us know which one it was.

 

thanks ill check
