Take the 2-minute tour ×  My 97 altima has been to the same shop
four times for the same problem. It will sputter and smoke(
black smoke) and has large loss of power under 3500rpms and dies
just about every time you depress the clutch pedal. The idle is
very rough just about all the time. When taken to the shop they
had replaced the throttle position sensor, the egr valve gasket
and the egr valve, the vehicle speed sensor, the distributor and
the cap and rotor, the knock sensor, and the spark plugs. Since
then the car still acts like it did before it was at the shop.
Now it has error codes p0100( mass or Volume air flow A circuit)
and 2 p0325( knock sensor circuit (bank 1)). Now I've heard that
it could be a bad mass air flow sensor..... how do I solve these
problems and fix my car so it runs like it should and not like
an overgrown golfcart with a horrible idle problem???

when your mechanic replaced all those other parts? –  William
