ve missing

[pas gab]

hi all after a bit of help,i have a VE SV6 2011 series 2.it has 116 k on it and always serviced,just done a trip of 2000ks and what it is doing from the start of the trip is i was driving for about 15 minutes all good like usual then as i was going up a hill about 80ks it started to have a miss,if you give it a boot full no miss,after about 45 minutes of driving i put some injector cleaner in it and half hour later the miss stopped,10 hours of driveing ,no miss,parked the car next day ran fine,following day took off and missed like mad and through engine light,going to check engine codes tomorrow,anyway drove it like that and put another bottle of injector cleaner in about an hour in the trip it came good again for about 8 hours of the drive,parked it and went to drive it this morning as it sat all night and its doing it again,what would you think i should be looking at as i first thought maybe bad fuel

After two bottles of injector cleaner, change your oil and filter. Someone who knows what their talking about will give better advice, but 1 or more injectors are on the way out or you have a spark issue. Spark plugs or coils. Stick a code reader on see if it helps identify the issue. They cheap

Get it scanned to see what caused the MIL to illuminate,
Not all DTC cause the MIL to illuminate.

The ks are low but quite likely to be a failed coil. Easy to swap on SIDI engine.

There is a lot of things that can cause a miss.
As Krusing said, get it scanned, see what it's doing.

Also check whether the misfire is always on the same cylinder which will help pinpoint the issue.

cleared code and ran fine for 2 days then started again ,same code came up.so i took that coil out and plug ,the plug had traking marks on the porslum and the tip was cracked,also plugs were stuffed so i changed the plugs today and at this stage running smooth,see what happens in next few days
