I was driving my car around(1990 CRX si) then i parked, started it again one hour later and my idle was really bumpy, it would go down to 1000 rpm then up to 1600rpm then back down so on so on..I don't know what to look for. Any feedback is appreciated!

 

ok on your throttle body look 4 the red braided cloth line under it is a flat head screw tighten it you'll be fine after that.be sure not to strip it.may be a lil tough to turn but thats it.let me know how u make out

 

Hey, ya i tightened that screw and my idle got alot lower but it worked! I am also going to clean out my throttle body because it is probably in need as well. Thank you for the help.
