ok well my car is a 1990 lx 4 cylinder auto...now i think that my low ideal is meesed up...ok well the thing is that my car can drop down to like 500 rpms some times and dies...so i think my ideal is to low...anyone know how to change this so tha tyou can explain it to a noob

 

On the throttle body there should be a screw to tighten up that pushes the throttle cable back a little should solve your problem although there is most likely something wrong if it just started doing that out of nowhere.Any service engine light or anything?I'm guessing by ideal you mean idle
How are you a noob with 400 posts?

 

lol yea idle...i'm still a noob...i can do stuff but not anything close to what others can...but ok i knew there were two screws but i thiought maybe there was something else i had to change...and this car i bought and it did it afteri bought it...there is no check engine...its nothing that bad but when i start it up and its cold then it does it...if i put it in drive and don't let it warm up a bit then it will do it...but once its running after a while i don't have this problem at all
