well i brought smash9002's bronco home. Guy sold it cheap to me as it is not running very well.
he replaced MAS sensor, crank sensor, TPS, EGR purge solenoid, Intake Air Temp, cleaned IAT - I took IAT off and verified it was cleaned and worked correctly
now it runs fine when cold when it is closed loop. after it goes to open loop. it has a interment run problem. Basically bucks and dies with check engine light coming on. A couple of times it has acted like it ran out of fuel and would crank dry. After a a minute or two of cranking it catches and fires. Almost like a old school carb motor.
Sometimes it seems that as soon as you let out the clutch it kills the motor. put in the clutch and it runs fine. Let out the clutch and it starts to die.
Other thing was that it would die and lose power to the tach, then come back up to speed. Which speaks to a electrical issue
codes are 565 EGR purge solenoid, and 522 Neutral Safety switch. the neutral safety switch was hot wired so it was neutral all the time. I put it back together with crimp connectors so it works correctly. verified if it is in gear that it will not start even with clutch in.Put it in neutral with clutch down and it starts fine.
verify on the EGR purge solenoid that when 12v is applied to it - opens.
kinda stumped at this point. I fixed what the error codes point to. Only thing I can think of next is that the neutral switch and EGR solenoid are on the same tree of the wiring harness.
any ideas?
