Hi guys I now have no hair left or money and yet still have a problem with my P38 D Auto 2001 running when warm.
I ran a thread some time back and had lots of useful advise on sensors etc which were all looked into, eventually the timing chains were found to be extremely stretched, replaced car runs well.... untill warm.

This is what I currently have:
Cold: Starts no problem, runs and pulls away towing or with air con on.
Hot: turns over for ever, will only tick over with AC off, once switched on drops to 200ish RPM sometimes stalls, turn off AC it picks up again but heres the catch only sometimes, other times acts how she should. The same with towing when warm, pulls like a train at one junction, get to the next and wont move, have to select netural rev car,idel resets, then pulls away again

Sorry to bring this one back but its driving me nuts?
It would seem that something (not sure what) is not commanding the computer (not sure which one), to a just the fuel correctly when warm. Or i could be barking at wrong tree?
Please Help
Thanks

As above - and I'd also consider having the FIP Timed correctly....if it struggles to start when hot, this usually points to the stretch in the FIP drive chain.

You say you have had the timing chains looked at - next up is to retime the FIP to take into account the stretch in the pump drive chain - check RAVE for the measurement tolerances - needs to be set up on a DTi to be spot on, you can't guess it unfortunatly.

Also live data will qualify the pump timings with the No. 4 Injector and the Crank Sensor.....

If the idle drops to stalling point with the AC on - I suggest the idle speed is too low - again this points to a miss timed FIP (As the FIP timing controls the idle speed too)....

As SV8 say's, plus the idle speed can be adjusted with diagnostics.
