Working on my son's 2003 Disco 2 4.6 BOSCH engine having fixed a bunch of leaks, pumps etc. I cannot understand why it won't idle under 1000. It fires up fine, revs well past 1000 but just doesn't want to idle. Any ideas? I didn't have this issue with my 2002 4.6 P38. It's got me stumped. Everything appears to be plugged in correctly, plus wires etc.
Your ideas appreciated.
