1988 Ford F-250 XL 7.5L Poor Idle Quality
Posted to Ford Driveability on 6/28/2002 2 Replies

Truck will idle smooth and consistent in gear. In Park or Neutral the idle degrades too 700 =/- rpm and rough. On start up it acts like the fuel pressure has been lost, but it has not. Base and computed timing ok. Basic IAC % is 35% at idle in Park , no load.....
