Bellato Donating Members 2,713 Member For: 14y 3m 27d Posted 19/07/13 07:58 AM Share Posted 19/07/13 07:58 AM Hey guys have an 08 FG xr6t and just took it in to get tuned and haven't been able to pick it up because it starts to miss and then dies. Car starts then you can give it a few revs, back off then about 20 seconds later it misses and dies.Tuner won't be able to do anything till monday now but just thought I'd investigate myself. It happens with the new tune aswell a stock tune adjusted for injectors. Tuner reckons it could be either be an issue with the injectors or a problem with my x3 Parts list include:Rapid cooler and turbo sideID1000's3.5" dump and catPW surge with walbro 460 pump82 deg thermostat0.75mm gapped NGK iridium plugsX3 (bought second hand but is unmarried)Anyone else had this happen?

He's gonna ring Herrod on Monday to check he has the correct data for the injectors Link to comment Share on other sites More sharing options...

Bellato Donating Members 2,713 Member For: 14y 3m 27d Posted 20/07/13 07:37 AM Author Share Posted 20/07/13 07:37 AM Yea genuine ID from Herrod's.Someone mentioned coils and I have heard of them causing a miss. Will you only get a miss from coils after you give it some, or even leaving it idle for a few minutes will it miss? I think the car was only missing after giving it some Link to comment Share on other sites More sharing options...

Bellato Donating Members 2,713 Member For: 14y 3m 27d Posted 21/07/13 05:27 AM Author Share Posted 21/07/13 05:27 AM Just to add, never had this problem before the tune. Also its happening with stock tune with data for injectors to run, still could be valve springs? I thought valve springs would progressively do something like this, not just start after getting a tune straight away? Link to comment Share on other sites More sharing options...
