Hi all
Still got a grumpy stag...
My 2002 M35 VQ25det had a wicked miss in it, replaced the coil packs and it was great for a couple of days, then it came back exactly the same. Replaced the coil packs again and same thing, fine for a couple of days then the miss came back just as bad. New plugs have been put in, and all the piping checked and it looks fine.
When at idle, it hiccups intermittently, and under acceleration feels okay until it comes on boost where it feels like it's running at about 80% power. It's running better than it was before I put the new coil packs in, but still down on power and not happy.
It still sounds like ignition to me. Thoughts? Crappy coil packs? Would the BOV affect it like this? Stuffed turbo?
If anyone has a set of totally stock coil packs that they are willing to part with I'll try that first.
I'm near Parramatta, but am willing to drive to a Stag guy to get this fixed. It's driving me up the wall!
Any help would be greatly appreciated!
Cheers
Andrew
