I also am having an idle problem that i'm hoping you all can help me figure out. At idle my alero seems to be fighting to find a good idle speed and even shakes the car back and forth. almost like it's lunging forward then resting back. does this make sense to anyone? by the way I have a 2.4 L 4cyl. and it's a 2000 alero if it makes a difference.

my check engine light is on. the hose that goes to the intake air temperature sensor did have a hole in it so i've since put the original intake systme back together. still same problem.
then i replaced all 4 spark plugs. all 4 old plugs had white tips on the gapped end. (not sure if this means anything) new plugs did nothing, same problem.
then i replaced the fuel filter, still i have the same problem.

all these things i really needed to do anyway cuz it was time but none of them fixed my problem. a buddy of mine let me borrow his OBD II scanner thing and it came up with this code P0171. can anyone decifer this for me?? any help would be great. thanks guys & gals.

great...now my signature doesn't work either. awesome. this just isn't my month. lol
