my rex with b16a1 has been starting up weird recently. after i start it up, it idles kinda low and vibrates. when i push the gas to rev it up a lil bit, it feels like it doesn;t want to give it any fuel then it goes up. after doing that like 5 times it stops. could my fuel pump be going bad? other than that it runs awesome as hell. also sometimes at stop lights the idle goes up and down a little bit. that is because of my type r intake manifold i believe.
any thoughts?

 

I had the same problem the other day.. I hadnt started the car in over two weeks... I dont know what it was.. after that it started up like a charm... do you have your FITV hooked up? my idle fluctuates untill warmed up.
