1997 tbird idle problem

[chacho44]

My gf bought a 97 bird with 59k og miles on it. Car is spotless in and out, we have noticed that in park only the idle kinda acts up. Does not drop enough to stall but it idles up and down good enough to wonder what it can be. I can live with it but my girl don't like it. I'm thinking it can be the iac that's going bad, dirty. Also thinking it can be a vacuum problem as well. Any others ideas on what this problem can be. Sorry no pics of gf, cause I'm a dumbass and don't know how to post pics

Try to clean out the throttlebody first and check for vacuum leaks. Probably IAC motor or TPS sensor.

Clean the IAC, MAF and throttle body, check for vacuum leaks, make sure the air duct is sealed between the MAF and T/B.
