Exclamation impreza bad running

]hi all problems again when new engine was fitted first of all it run rough lumpy when reved then sorted it self out every now and again it would do this but i would stop and wait 15 mins and then car would run fine again but last week this wasnt the case i started car up got bout 5 mins away from parents house car felt a bit slugish anfd then the rough running came back seems like a missfire so i cruised home very slowlyand hasnt run right since then
i have done commpresion test all cylinders 145
checked coils and plugs 1 coil was cracked replaced that
checked all intercooler pipes etc
oil level is fine
none of above solved my problem so
only thing i have found is if i diconnect maf it wil idle bad BUT lower rpm is smother till u get to 3000 rpm then rough running is back could this be my problem as i am low on money and need car to get to my new job
thanks guys has any1 had same problems il give anything a try its just buying new bits i wana be sure before i spend
