T 5 Turbo miss fire - check engine V70-XC70 1998

My T 5 Turbo really flies when you get on the turbo, but if pushed to hard it stumbles and hesitates briefly and then smooths out. If the check Engine lite is off it will come on until I have my mechanic check the code (always and cylinder miss fire) and reset it, so the check engine lite is almost always on. The power and boost is great.

ANSWER T 5 Turbo miss fire - check engine V70-XC70 1998

What kind of spark plugs are you using. They shoud be copper core and gapped to .028 in. You should also be using premium gasoline to rule out knock sensors retarding the timing.

I don't know about the plugs, I'll look into it, and probably replace. I use only premium.
Thanks for the tip
