When im driving along my car will feel dead every now and again. i got my foot planted and it wont rev. then all of a sudden it clears itself and goes better.

also when its on idle it sometimes idles lumpy and hunts.

ive changed
coilpack
leads
plugs
fuel filter

cleaned iscv

was still the same.

so unplugged the maf and it ran better.

so then changed the maf with the one off my old car.

it hasnt missed or flat spotted yet but idled a bit lumpy in traffic this morning.

but it defibnately feels underpowered.

anyone got any ideas on what it could be?
