    so i have an 89 crx si...motor revs nice like a peppy sob.....but when it warms up and starts to get to a nice idle.....it goes to about 500 and sounds like a go-karts idle.....the exhaust has this annoying idle lie...pop pop pop pop pop pop......is it my ebay exhaust or is it sumthin wrong.....no cel no codes.....it revs and drives fine....and why is the idle so low at 500rpm? isnt factory between 750 and 800?......help would be appreciated like always :mrgreen:

    and btw...new cap...rotor.....wires...plugs....pcv....air filter...and even shot some injector and throttle body cleaner in it to see if it would clear up nething....and nothin

    I brought my idle down to 500. Check the run for the throttle cable - make sure it's in it's hold-downs.
