anybody know these cars? i keep posting with no responses

[MYFREE95,240SX]

cars idle is screwed... in gear when warm only, will sputter and stall happens in reverse mostly when accelerating it sputters alot until about 3 grand then runs fine. car is a 95 ka24de with 207000 miles recently i have done.... injectors, wires, distributer cap, plugs, fuel filter, battery, 2 alternators due to a charging system issue that i think is fixed now. ummm.... thats about it. this sputtering issue is not new and was doing it before anything was replaced i cant find a vacuum leak and is now alot worse after doing injectors. when i disconnect mafs idle is really nice. please i need to diagnose this asap it is my daily driver and i need it to work. funds are low so start with inexpensive things. and im not some 20 guru so laymen terms help. i have the Chilton's for my car but they show a completely diff. engine then mine and i cant find half of the things they talk about. please help im here twice a day minimal with time to work on her.

are you guessing?

Use fuel injection or carb cleaner, to clean: MAF, intake piping, throttle body.

What will end up saving the day is cleaning your IACV (very common problem, esp w/ high-mileage KAs): http://www.tamparacing.com/for....html

not the iacv did it this weekend getting a masf this week mines clean as a whistle. and im pretty sure its gonna be a sensor since it only starts happening after warm up when it starts looking for feedback so im doing masf, coolant temp ad both o2s over the next couple of weeks

It sounds like your Mass Air Flow Sensor is failing under load when demand is increased. Check the inside of the MAF tube and look at the actual sensor wire for any debris, something like a fragment of a leaf will cause an altered reading.
