air intake problems

hey guys i need your help real bad, i just put this air intake in my 91 sentra 1.6 here's a link http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&viewitem=&item=180203741498 well the thing is that now my car doesn't work or turn on with the remote starter it tryes to turn on once and that's it like if the RPM was to low or something i move the idle screw already but it doesn't seem to make any difference, and the same when i try to turn it on by hand it tryes to start but i gotta hit the gas to make it turn on that's the only way it will turn on a cold start but when the car is warm everything works fine, remote starter and with the key, and all this started happening after i put the intake what can i do is cold here in chicago i need to get it working right again and is frustarting
do you think is the fuel regulator?? or what else can i do ? HELP ME!!!!!!!!!

ummm theres several possible issues. check fuel pressure with a guage, and check vacuum at idle and off idle. the only way for it to be a result of the intake installation is if the MAFS was having problems or there was a vacuum leak.
