Well the car had a very serious misfire to the point it was undrivable,

Today, i have fitted new dis packs and now have spark on all cylinders
also fitted new spark plugs gapped to 0.7mm

It is running alot better but there is still a slight misfire when you push it hard

Anything else it could be?
The car is boosting about 15 psi, seems abit high, don't know if it has been remapped on the past or not,

It doesn't feel as savage as a fuel cut, just hesitates
Could it be the fuel filter?

Any help appreciated

Cheers

Do you have 4 coil packs on that year ?

Yeah mate
Just changed all 4 and have a strong spark on each

I had a problem like that, assumed it was misfiring when infact it was a loose injector connection. So intermittently jerking. Hope it helps.
