replaced alternator, now car will barely run!

[greathuskie]

car sounds like its trying to run, it fixed my voltage issue but now i dont know why it wont run? i put in the 90amp alternator from autozone, but what is the issue that would cause the car to barely run and die if you arent on the gas?

Did you plug in your voltage regulator? Why did you replace it in the first place? You may not have had a bad alternator. Come on more info sir! It's possible it's bad straight from vatozone. I would also go with a fuel issue/battery issue/vaccuum leak. More info on why you replaced it in the first place would REALLY halp

replaced in first place because when id start my car prior to it, it would drop my voltage to 11.2 or so volts, now with this one im above 13 but my car wont stay starting for more than a few seconds with me pushing the gas.

Test your battery sir.

battery is brand new, purchased today.

+1 for test battery also check your fuses you could have popped one in the alt installation process causes all kinds of funky problems.

i just bought the battery today, and the alt fuse is fine, the only fuse i have blown is a fan fuse and taht was blown previously.

so my IAC swap was ghetto-soldered but it was never a probelm before...i think my battery light is on, why would that happen??

so i turned the fuel pump on with my link, its at 43 psi, the fuses are fine, battery is brand new, i dont know what else could cause this! spark plugs look ok, kinda black.
