wasup guys i went today to look at a 91 ls integra and everything was great and everything except the idling. the rpm would go up and down up and down. he said his mechanic friend said it might be the fast idle sensor? and he said those cost around 250. so i was wondering could that be the problem? he said it idles up and down when the cars cold but when its warm it idles steadily around 700 rpms its a rebuilt engine so yea. could anyone help me? b4 i buy a piece of shiet. which i doubt because when i test drove it it was smooth as hell. just the rpms were going up and down.
