Fiesta Turbo running problem

[benm3evo]

Hi All,

I have Fiesta ZVHT with a really bad hesitation/flat spot when accelerating. Have checked leads, plugs & coil. The problem is amplified when the boost is up, misfires badly & pops & bangs a lot on over-run.
I'm thinking it's a fueling problem possibly? It has had a recent setup & chip at MSD so that should all be fine.
I've had the suggestion to remove the fuel pump damper as this could be the cause so will try that but just wondering if anyone has any other ideas?
Thanks for any advice.

Thanks for the reply mate. I had actually tried another coil, forgot to put that in original post!
Anyway...problems sorted now, it was the fuel filter! Bit strange I thought as it only had a new one about 3000 miles ago. Never mind.
Cheers
