1999 2.5 986 misfiring while accelerating

Hi, thought I would see if anyone has had this issue. Car was misfiring, and wouldn't idle. Had fault codes 301,302,303 (misfire). I change the spark plugs and coil packs , codes away but not cured. Changed the Maf sensor which has helped as does idle from cold start now. Cold or at temp when trying to accelerate , it pops and holds back . Running lean ? Was going to look at lambda sensor next ? Not wanting to just change for the sake as no codes now, any ideas?
