Title: Engine Cut Out
Post by: oRi on February 20, 2005, 11:06:43 AM
Hey guys

Seem to have an intermittent fault on the FD, basically she cuts out on me quite often under harder then normal breaking. Any ideas what could be causing it. Its never a difficult job to start again tho.

Cheers

Stu

could be a lot of things bud.  does it labour or miss before cutting out?

Could be anything from the fuelling at idle being a little dicky or could be a clutch thing not disengaging properly.  

Got any more on what\'s happening?

nothing strange really happening. Just if you are approaching a roundabout and you perhaps have to stop a bit quick it just stalls. Restart it and its fine.

stalling not good.  I\'d suggest getting it to someone to have a checkup.

Your engine is getting very tired,to get around it because your car is an auto turn the idle up a bit.

Sorry to hi-jack the post, but...  How do you turn the idle speed up?  I have a manual twin turbo which has started to idle a little lower over time.  Its not a problem, just be nicer to get it spot on.

Thanks  :)

Title: Idle Speed Adjustment
Post by: jonrx7uk on February 22, 2005, 09:23:23 AM
Idle speed adjustment:

bring engine up to normal operating temperature
connect TEN and GND
connect a tachometer to diagnosis connector pin IG- and a chassis ground
make sure the wax rod operated lever completely separates from the fast idle cam
adjust idle speed to approx. 725 rpm by turning the idle speed adjusting screw located UNDER the throttle body between the two 10mm cap nuts that attach the charge air pipe to the throttle body
if the idle speed is too high with the adjusting screw fully screwed in (clockwise),    unlock and turn (counterclockwise) the primary throttle stop screw to give you more    adjusting range for the screw under the throttle body.
while adjusting idle make sure the fans are not running
remove the TEN-GND jumper and verify that the ISC system takes the rpm up to approx. 850
