I put new fuel pump, mass airflow senser, oxygen senser and it started to work fine and back fire once and a while but very often. now my altinator just went and burnt out two fuses so i replaced them and at take off once and a while it has no power then back fires. then if u let off the gas pedal and step on the power is back and it takes off like nothing, any ideas?

The MAF is in the flex hose that delivers air to the engine, it has a 5 or 6 wire connector going to it.

after you did that did you hook it to a car computer to reset the lite? most need this and you can go to a auto zone and rent the computer for free just a deposit and then you get that back. the computer will do it almost for you.

the symptoms indicates lean mixture. you have to clean the nozzles and the throttle body without doubt.

My truck 1988 f350 w/ 460 does the same thing and the solution was simple for me, Check your vacuum lines and vacuum plugs when my truck backfires it blows the vacuum plugs off and then it runs poor untill I re-plug them. Hope this helps

THE POWERSTROKE IS WHOLE DIFFERENT ENGINE THAN THE NON TURBO 7.3..

when i bought it, it was acting the same but it was the mass airflow senser, it was running fine yesterday until my altinator went when i was driving so i limped it to a parking lot with just the battery power and its never been the same.... any ideas where to start? it idles rough and no power when putting it in gear at first until u get the rpms up
I just blew my motor after having similar issues....throw a conneting rod thru the cylinder wall.
