Dprem Member 37 Member For: 10y 7m 4d Posted 02/09/14 12:06 PM Share Posted 02/09/14 12:06 PM I have had an issue for a while now my 2010 fg f6 ute 30k on the odo, growler intake and catback I have had it for 3-4months now .a while ago after filing up with shell 98 ( first time normaly bp98) started missing excessively replaced fuel filter (opened it not drity) got better. after many tanks of bp 98 it was still missing cyls 1 and 6 mainly on cruise 100-110kph than randomly at other times.replaced plugs to standards gapped down missing got better only on cruise 100-110kph not randomly 1 and 6 cyl again.replaced coil packs it bacame perfict on cruise random missing around town and after coming from hwy into town now on cyl 2 nd 5.has anyone experienced this of have any insight to me it is looking like fuel ie injector dirty fuel lines still? or possibly valve springs?any help would be good cheersdarron Link to comment Share on other sites More sharing options...

Mr_4.0 Member 1,096 Member For: 13y 11m 1d Posted 03/09/14 01:05 PM Share Posted 03/09/14 01:05 PM Does it do it more often as you back off throttle? Even if doing 100kmh but just lightly get off. Then try get back on? Link to comment Share on other sites More sharing options...
Dprem Member 37 Member For: 10y 7m 4d Posted 03/09/14 09:15 PM Author Share Posted 03/09/14 09:15 PM light throttle cruise and moderate throttle up sight hills, seamed to go away under heavier throttle more prone when engine is hot Link to comment Share on other sites More sharing options...
Mr_4.0 Member 1,096 Member For: 13y 11m 1d Posted 03/09/14 11:40 PM Share Posted 03/09/14 11:40 PM Obviously check for simple stuff like earthing in your coil looms. Could also be a sign of coil drivers in your PCM getting old. Link to comment Share on other sites More sharing options...
