04 gu bus...

Well got the bus all back together... cleaned all the gunk frm the manifolds... blockd off the egt...getn a solid 30psi at full noise and it pulls hrd.. have a couple left over bolts.. haha must be for a wiring bracket or sumthing but 2 out of about 65 or sumthing isnt to bad. No leaks... no weird noises... the high idle issue is gone... out of 10 times i turned the key it fired up 8 times... so i dont knw whats going on there... it might have a bit of air still in the system or it might need another earth strap... will be adding a couple more earth straps.. one frm battery to block and block to chassis... still only early days but i think i might have fixd my gremlins... haha prety happy right nw... nit to bad for a wood butcher.. 4g bak in my pocket...

Yea sweet outcome.
Did you throw new glow plugs in?

Ye new glow plugs... new gaskets.. new vacume hoses.. well u wouldnt believe i went out fora quick 4b and on wayy home it started idleing high again.... wtf? Got to be something else besides the injector pump? It was working sweet b4.. no high idle.. easy starting.. nw its like same as b4? Thoughts? Crankle angle sensor, bad earth?

Did you run some new earths> , bummer I thought it was sorted.
Vacuum hose is cheap enough to replace, Do one thing at a time
swap the blue ECM with the aircon one to test costs nothing
Crank angle went on mine and showed up as an error, symptoms
limp mode, back off and try again ok till it happened again

Come out a few hrs latr.. started up first pop no high idle... seriously... wtf.. its got to be something silly... havnt done earth straps yet... another idea might be a faulty injector?

so something has "RE-SET" itself do you think

will look into more earth straps see if that makes any difference...and check resistance of current earth straps...

FYI on Tojos they have an earth strap for different sections of the 4x4
EG front of engine bay,,, rear of engine bay,,,, front of cabin etc etc
Good luck with it MH

How high is high idle?
Is it about 500 rpm higher than normal? These have a high idle switch "sort of a choke" and also hight idle if the aircon is switched on. The switches just tell the engine management to turn it up a bit. Wondering if its missreading and turning the revs up.
