Phil, it ONLY has problems OFFthe throttle correct? when idling or coasting?
let me know! thanks
Yes I first noticed it cutting out when taking my foot off the throttle, but now it cuts out if I start it and leave it idle. I haven't had problems on acceleration. Thanks
Thanks for the clarification.
is the idle real lopey
and rpms fluctuate?
if so this could be an issue with the EGR sticking and not being able to fully close
this will cause obvious issues at idle that will not be noticeable at cruising or accelerating
the other possibility would be the throttle being dirty which could have caused it to lose idle adaptations that are set.
if that's the case you have to remove the throttle in order to clean it, then you have to re-initiate idle volume learning with a scan tool
if you need anything else let me know please.
The problems I described were on Saturday, I didn't do anything with it yesterday but have just started it, it idled for 5 mins ok so I took it for a run for 10 mins then let it idle again and it seems fine. One thing Saturday was the outside temperature was much colder if that could cause any difference or is it an intermittent fault?
Someone suggested the suction control valve on the fuel pump. Could that cause this fault?
I do see ALOT of SCV problems on these trucks.
In most cases though they will effect the car while driving as well though and even cause stalling.
I do find I have to be gentle on the clutch starting off or it will stall but assumed that was just the clutch being sharp! Are they prone to that or could that be related to the fault?
