check, clean or replace the CKP (crankshaft position sensor) ... and check the wiring is not damaged !!

If you brought your vehicle into my garage with the symptoms your describing, the first thing I would be checking after the coils is the CKP ... It produce's these symptoms when dirty or worn ! have a look at this first and repost with the result's and we will take it from there !! hope this helps .. let me know
