The car's a 95 RA with a ScoobyECU remap. Recently has been quite hesitant below 3k, but fine above it. Haven't checked the plugs yet. It's a low mileage car (29k) - could it be the coil packs?

 

I think coil packs are your best starting point, mine had been hesitant for months and months, when I checked coil packs 2 were cracked.
Being a tight **** and not wanting to spend circa £70 each for new ones I set about fixing the cracked ones with great success.
I was donated some Gel Pack (dont know its proper name as was in a lemonade bottle and an old paint tin!!), the stuff they use to coat the underside of jet skis and power boats, it is oil proof, petrol proof, heat proof and sets to a rock solid, sand paperable coating.
I gave each coil pack 2 coats all around the cracked bit, one coil pack even broke up into bits and I stuck it back together with this stuff.
The car now has absolutely no hesitancy and I can really feel the difference my ScoobyECU makes to the performance.

If it is not a coil pack problem then there seems to be loads of other areas it could be based on previous threads I have read on Scoobynet.

 

Don't you know whats wrong with it?

Perhaps an "idiot" would have a better idea......................
