Answers :

4.3 TBI (throttle body injector) You dont have a TBI you should be equipt with a CSFI people in the field call this the spider injector,they inject fuel into tubes for each cylinder , as for the fuel pressure it should be 54 psi to 60 psi,and this is for a 4.3, The CSFI system does plug up which causes rough idle due to the poppet valve or seat,to stick open or closed,Ive ran fuel injector cleaner that has been sucesfull maybe you can try that
