I've just had a look through some of the posts and I feel that the only lasting solution is to change the coil packs.
I spent too much time earlier this year tapeing and sealing and thought I had the coil pack fixed.
Just when I needed the car to go driving around Europe it let me down big time, I was well pissed off.
Got new genuine Nissan coil pack (part number
22448-AA100) and it cost me €167.70 and that included VAT and carriage.
I should have just gone and got the new one at the beginning and it would have saved me a lot of grief.
Hope this helps some of you.
