E320 1994 dies for a second with full throttle can feel a small hesatation when acceleration with half throttle I think the engine miss on one cylinder I got new fuel pumps and ignitions wire don't think it's the ignition coil could be a spark plug but they are not old I check them in the morning.
Next to check is the fuel injectors.
Anyone who haved this problem.

have you tested mass air flow sensor

car off disconnect sensor take it for a drive
comp will go back to the last good reading it had from the maf sensor
if it dosen't play up change your sensor

maf will cause it to misfire/backfire run like ****

Been thinking about that but the MAF sensor is not that old but I guess it's possible but there is no code on the code reader
