    engine trouble, what can you recomend

    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

    There are a number of possibilities but the MAF or CPS would be at the top of my list of suspects.

      Have you changed your fuel filter? Might have gunked that up with gasket stuff...
