Re: 92 v6 surging idle

Welcome to AF.

Did you set the IAC before you installed it ?
And what is the air flow you replaced ?

If its intermittant I'd check the wiring for the MAF or hav it tested.
Usualy surging is from a vacum leak, but it could even be a bad fuel pump. WHich you can check the fuel pressure to see what it reads.

Lastly it could be something in the emissions system going bad.
