erratic idle

That is one thing I forgot to add to the list (throttle butterfly position)... that got down about 20-30k ago !!

I wouldn't mind checking the fuel pressure next actually.

i have a haltech E6X and was able to but my afm in the shed ... made me feel good extracting yet another lucas part from the RR... it runs better with the haltech and there is nothing blocking the airflow except the filter plus you can program the ECU as you like ... ( dont loose the original maps incase u stuff it up)
i have heaps of pics if anyone is interested...
cheers

Hi Rangee..... very interested in the pics, post them here or email them to me, PM if u need my email address, also interested in what you need to do to put the haltech in and what sort of cost is involved !

M.

ok so how do i post them here?
thanks

Also has anyone else got anymore ideas ?

Matt.

yeah all good check out album 4 i think ... just put a few more in too ...
hope u all like ...
i strive to please ....

Just a couple of suggestions champ the fuel pump contains a non return valve which i found to be a problem in mine this may not be the fix but simple to check fuel psi running and not running.The other pos is you
could be chasing a non mechanical problem such as carbon build up in
and on intake runners,ports and intake valves i have carried out many
carbon flushes on engines with running problems with excelent results.
With the poor quality fuel they add PNA poly-nucular-aromatics to raise
the octane however the PNA seperates from the fuel once heated, this
happens as soon as the fuel reaches the fuel rail in the engine then passes
through the injectors which is then sprayed into the intake port where it
also hits the valve.The heat from the port and valve then turns the PNA
to a waxy residue which once cooled forms what we see as carbon.
This then causes running problems due to the carbon being like a spunge
it actualy absorbs part of the fuel being injected then becomes saturated
drips fuel and causes a rich,lean rich,lean effect.
look around for someone with a on car ultra sonic carbon flush should
cost around $175 good luck SKIDS [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

8) thanks skids, as you say i also have had success with carby cleaner pressure pack, especially at the stepper motor and the hoses. also i found heavy buildup in the plastic t fitting where it t's into the throttle body and the plenum - there is a restrictor in the little tube which was blocked on mine.
i had a new stoppage problem last night which i think is the battery dying.
so if it gets me to battery world this morning they will get a sale, otherwise mr racq will win a sale!
i have fitted a fuel pressure guage to monitor that for a while, but have not driven in the same conditions that normally cause me problems.
and skids, welcome to the site.

Would the ignition amplifier cause idle problems ?
