got the front right mount on, couldnt do the other two,was given the wrong one, so it will be tomorrow before i can do that. well the car was still starting and dying, i looked, checked all the the conectors,lines,etc to see if any were broken, nope. Well i recalled that i made a new gasket for the map sensor, because when i took it out to inspect it, the gasket broke. so i unconnect it, and start it up, runs fine! hook it up dies!
so i left it unhooked, so the car runs fine, so what is the point of this goofy pos on here, if it has no effect on the car's running condtion?

also the battery light is on, yet the alternator works fine, and the battery is good, i have a 500 watt amp hooked up to the car, would this cause the computer to think the alternator is no good, because it thinks there is a drain?

Check the connections on the alternator.

The reason why the battery light is on is because the battery is drained probably from excessive cranking and stalling. The alternator hasn't had a chance to charge the battery since the car hasn't run long enough. Once the car is running and back to normal, the light should go off.

You need the maf sensor to be hooked up otherwise your car will not idle and will run very rich, which is an easy way to kill the O2 sensors. The maf sensor measures the amount of air coming into the engine and adjusts the fuel mixture for the correct air/fuel ratio at a given throttle position. The only reason why it runs is because the ECU defaults to open-loop/limp mode to keep the motor running when a sensor is not sending a signal to the ECU. It will run in open loop, but not well with very little power and will get poor gas mileage.

its not for me, if i leave it unhooked, it idles fine, and acts like a normal motor, but if i hook it up, i have to keep it at 2000 rpm to keep it from stalling. it did not do this untill i replaced those motor mounts, which is odd, but i dont get why it runs fine with it unhooked.

That explination has already been given.
IF it is not the MAF, either by coincidence or something getting pinched in the harness from RUNNING THE CAR WITHOUT MOUNTS... I'm not sure.

yeah the dude said my car would not idle, and run in open loop. and have little power, however, its running in closed loop, running in idle, and has plenty of power
