ok... i did search for this and couldn't find quite my problem explained....
(i have a 90 crx si)
my idle would rev it self up to about 2500 then drop to 700 and repeat... just rev it self... and pretty quickly... (this was about a week ago)
the ecu was throwin a code 1 (02 sensor) so i went ahead and replaced that...
the problem seemed to go away for a little bit... but now its back... and not at every light.... like every 3rd light i'm sitting at in neutral it'll start doing it...
i've replaced my fuel filter (as it needed it anyways) and tried using anohter o2 sensor...
if anyone else has had this problem and can give me some possible soloutions that would be great.... thanx guys
my only geuss is that it could be a map sensor or a tps???? but i'm not too shore and don't have $$ to throw into tons of parts for trouble shooting... but may have to
