V6 stalling/poor running
« on: 19 January 2007, 08:48:54 »
hello guys

this problem started two days ago and is now getting worse

at first the car started to run badly at idle speed
then the problem went as quickly as it had appeared

then it came back again!  when it happens, sometimes it stalls. then i restart it. it stalls....restart....stalls....
also, it seems there is a lack of power as you pull away. the revs take a while to pick up, then it seems flat for a bit, under 3000 revs

any ideas on where to start looking would be very much appreciated!

thanks,   stu

Any EML, if not, does EML come on with ignition?

no EML, but light does come on with ignition, and go off as normal

i'm sorry about the explanation of the problem - its just a tricky one to put into words!!

i did clean the IAC valve the other day - it was fine for two days after that - then the problem started - could that be related?

thanks,   stu

How did you clean (carb cleaner)?  Did you oil afterwards?

The power loss could be related to multirams, check they work properly as well...

When it stalls, is it a sudden stall, or does the engine hunt a bit?

WD40 is not a true lubricant.

Is your problem happening when you're running on petrol or LPG?

Not really. A light oil is what you are after, and just 2 or 3 drops...

The multiram won't cause stalling, but will affect power at different rpm.  Fix the stalling issue first...

Also, air intake leak may also give stalling/uneven idle symptoms...
