First and foremost I apologize for my lack of Car knowledge, It is my wifes care and Im not a mechanic by any means.

Today we attempted to start her car, its a 2000 Honda civic 2 door, i don't know anything besides that, engine type etc. Anyways, It didn't start, we figured it needed gas as we parked it on a slight hill, we put gas in it, and it still didnt start, so i popped the hood cleaned off the battery terminals, hooked them up again, No go. So we take the battery to kragen and they replace it, battery was dead. so we get a new battery i put it in, and hook it up. Crank it a couple times, and then nothing. I try again and the car starts right up, but its idling at 2k roughly. and it putted to life, like it struggled to turn over. any suggestions on what the problem could be?

Thank you.

well..im not pretty sure, but try having ur throttle cleaned up...probably d sensors..
