Re: 92 vic mechanical probs
I would also replace the fuel filter. And a way to check to make sure your IAC is working is to unplug it while the car is at idle and if the car stalls then the IAC is working like it should, Because cleaning a IAC does not always work so they are replaced rather than cleaned. I would check the voltage at the TPS sensor it should read .5-1 volt at idle and at WOT 4-5 volts. I would also think about cleaning your MAF sensors.
