      i have a 94 explorer with a weird idle problem it is idling at about 500 rpm and while idling it is kind of rough and and has a slight putter. It had codes for dpfe and iac replaced both of them and cleaned maf, codes went away but idle never changed. New codes appeared they are 157,411,412,565 and while in gear if you press on the gas to hard the engine dies out. Please help

      i would check the fuel pressure. Check all the vacume lines for a vac leak thats probly whats causing it to stall when the throttle is open suddenly. just as a start

      You may want to trigger your computer to relearn your idle. You can do that by leaving the battery disconnected for 30 minutes.
