I searched and these have been brought up before but no good answers but ok so....

its a b16 btw........first problem is the idle....after it warms up it will sit at about 1200 rpms give or take...idk what the deal is with that and...

SOMETIMES...when I am driving if I start to go up a hill or sometimes it doesn't even take a hill...the car will bog down until I take my foot off the gas then it will go back to normal for a bit then it will do it again.....any ideas? would it be fuel or spark?

thanks alot
