runs rough/misfire between 3k-4k revs

DJ Walkers

Ibiza Cupra 247.1BHP
recnetly had 1 of the coil packs go, replaced it and runs fine except between 3k and 4k revs where it runs rough like when the coil went, it cuts the boost too but when i dip clutch or change gear the boost returns until i hit 3k again.

is this a sign of another coil going?

also changed maf today no change!


cheers

Would get it on vag-com to checked fault codes and find try to find definate cause. May save you money replacing parts that aren't needed.

What are the plugs like, when were they last replaced, worth taking them out and checking them.
