I think the cars done it since I got it. seems like between 50-60 does it a lot. its abnormal. not like im just letting the rpms get too low (seems to do it even at high 2k rpms) like its losing power but I compress the clutch & rev it or downshift & im usually fine. car has a bama tune (hiccuped before tune) & 4 of the 6 "cats" or w'e theyre considered (there where 6 larger cylinder cat like objects on it lol) have been removed. still the issue consists after I had bama shut off the rear 02 sensors & I replaced the front two 02 sensors. I just changed the spark plugs, wires, & ignition coils before the tune. my next guess is maybe MAF or vacuum? just curious if there any suggestions before I attempt to throw money that I don't have at it lol
Ok keep in mind car used to be automatic. P0750 P0755 P0720 P0708 P0743 P0354 P0713 P1000 P1746 P1900 P1702

Mine ended up being plugs, which I suspected. Replaced them all with Autolite HT1 and it runs smooth as silk.
