Power loss

ok i have a 92 firebird with a 3.1 v6 and my check engine light is on... it comes on after about 10 minutes of driving and then i begin to lose some major power... autozone hooked up their obd1 and found it to be a code 43- tps out of adjustment so i replaced the tps and i also cleaned the egr valve and cleaned the idle air sensor... the guy at advance auto parts said it just needed cleaned, but the autozone guy said it needed replaced... ideas?

some times it's better to replace them than to clean them becouse they could alredy be dameged i personaly had tried to cleaned them with no resolt
i would just replase it with and ac delco brand you cant go wrong with an OG part
