Recently got my 08 Gt retuned a month ago, drove it home 2 hours and didn't drive for a few weeks later. I changed the spark plugs out and went to drive it, but now it will not run. Acting like it is not getting enough fuel, but only acts like that after 1st gear, can't get it over 40 or it will completely die. Would the new spark plugs have anything to do with this? or bad tune?

Had platinum plugs then switched to iridium. It idles fine and run fine until about 20mph then it begins cutting out, jerking, misfiring, and running bad.

Returned from where and what was done to it before you got it back?

Sorry, I got a new tune. I had a Bama tune, but I got someone to do it. Mods are, bbk long tube heads, hot rod cam, borla exhaust, bbk 62" throttle body, Bama CAI.

Nothing has been changed beside the tune and the spark plugs.

Welcome to the forum.

Start a new thread in the Tech section for your year Mustang, you'll get alot more responses from there.

Good luck

I would blame the tune more than spark plugs.
