jay384 New Member 15 Member For: 12y 3m 15d Posted 31/12/14 03:56 AM Share Posted 31/12/14 03:56 AM (edited) Was driving to work this monring and discovered after pulling up at set a lights that the car is "idling rough". Has anyone else had this issue in the past?Ute is Stock standard always run on BP98. oil changed regularly. doesnt get thrashed ( I get roughly 800KM to a full tank) I should point out that the pugs were changed 10,000ks ago and it went perfectly until this morning. Drove home last night without a drama. Its idling up and down betweeen 600-750 rpm and sounds like it has "blower roll" I have the OBD scan tool so ran the fault code check and the only fault that came up was the grey "theft" codeNothing has flashed onto the dash at all. Bit concerned as its never happened before. Any advice is or input is welcomed Edited 31/12/14 03:59 AM by jay384 Link to comment https://www.fordxr6turbo.com/forum/topic/89834-rough-idle-2011-xr6t/ Share on other sites More sharing options...

stretch4660 Member 122 Member For: 12y 3m 29d Posted 01/01/15 03:37 AM Share Posted 01/01/15 03:37 AM I had a pretty similar issue with my ute, idle up and down, runnin like a dog, as soon as you accelerate she'd come good. Turned out to be Variable Cam Timing sensors not advancing enough at idle. Tuner said most likely cause was wrong oil (to thin) had been used, so I changed to a 10W-50 and she runs pretty sweet now 1 Link to comment https://www.fordxr6turbo.com/forum/topic/89834-rough-idle-2011-xr6t/#findComment-1520541 Share on other sites More sharing options...

Any good mech should be able to take them out & give them a flush. During BA, they released Ecu flashes that added a purge command at startup iirc Link to comment https://www.fordxr6turbo.com/forum/topic/89834-rough-idle-2011-xr6t/#findComment-1522190 Share on other sites More sharing options...
jay384 New Member 15 Member For: 12y 3m 15d Posted 13/01/15 11:47 AM Author Share Posted 13/01/15 11:47 AM going in Thursday to have it looked at. I have noticed over the last week since the oil change that the idle is getting a tad better. Still going to have it seen to though. Might "need" a tune to help "fix" the issue.

demon1300 Member 435 Member For: 13y 2m 12d Gender: Male Posted 13/01/15 12:19 PM Share Posted 13/01/15 12:19 PM Maybe timing chain tensioner guide top has broken off and timing skipped a tooth or two? This is pretty common for these engines. Link to comment https://www.fordxr6turbo.com/forum/topic/89834-rough-idle-2011-xr6t/#findComment-1523621 Share on other sites More sharing options...
