so my 84 325e is running terrible, i start in first and once i hit 1500 rpm or so i lose power for a second and then it come back on. same thing happens in every gear at low rpm, when i leet off the gas and coast it has a sound that happens on occasion that sounds like it is miss firing, this morning for the first time i stepped on the the gas in low rpm and it barley moved sounded like i had 3 cylinders going.
i took it to my local bmw mechanic and they said it could be my mass air flow sensor so i ordered one and they sent me the wrong one, but i still dont believe it is that. ryan also suggested my tps so i changed that and nothing changed. this all started happening when i had my old gas tank that didnt seal at the top of the tank where the fuel pump goes in, i used make a gasket to fix it untill i could get a new tank, i believe that maybe the make a gasket leaked into the tank and damaged the external fuel pump (i already replaced the in tank pump when i installed the new tank) also i was thinking it could be my injectors ( i put zmax and sea foam treatment already and it did nothing) so im at a loss. if anyone has any idea what it could be i would apreciate the help very much
