What have you tried to date? Are you sure the sucking sound is from the throttle body and not due to a vacuum leak? A vacuum leak, which will make a sucking sound, will also cause an erratic idle. Do you have access to a scan tool that can provide datastream results? If so, what are the short term and long term fuel trim (STFT and LTFT) numbers? Did this issue happen to just start after you checked the air filter or performed some other maintenance? You should inspect the intake air tube to make sure it is secure.

Which engine does your 1998 have?
