Did you check for codes? There can be codes with no check engine light, I would start there first. It could be that your maf is bad, no need to get a new throttle body unless you want one, the tps sensor itself is around 25 bucks. The iac might need to be cleaned or replaced, kind of hard to tell without seeing any codes.
