Asked by Darrick Mar 27, 2012 at 02:51 PM about the Ford Bronco II

Question type: Maintenance & Repair

i have replaced fuel pump, filter, fuel regulator, plugs, cap and wires. blew out the fuel lines, cleaned out the fuel rail, dropped tank and drained cleaned and refilled, cleaned out injectors, replaced air cleaner, and cleaned out the plenum. I have reset the timing to 10* BTDC as specified on the tag in hood compartment.  Still when driving it keeps hesitating. I have run out of ideas in my non-mechanical mind.
