engine sputter
I own a 86 bronco II and this truck really frustrates me. When i am driving it will start to sputter and sometimes even spit back through the intake. If i put the pedal to the floor it will sputter for a second then open up.. Let go of the gas it will run normal for a little. Doesnt do it all the time. its like a switch..sputters i keep the throttle the same then like a switch it runs normal. The thing that bothers me is it runs good for days sometimes then one day it runs like crap.....now the things ive done to it..map sensor tps ..2 new fuel pumps..module...coil...ign sw...even tried new ecu.. and i have put on fuel pessure gauge and runs normal. ran for codes and no codes come up. i do have new plugs wire and cap and rotor. well i dove about everything to this beast. hopefull this is enough info..

i have changed spark plugs twice. timing is correct. I put on a new fuel pressure regulator. and last but not least a new pick-up i just put on last night. and i redid my timing again. no sputtering this morning so far..im crossing my fingers. i did put on o2 senser. i have a snap on scanner and it was cycling properly
