FD weird idle and A/C problem
I will apologize ahead of time because I have been posting so many new post for different problems i have with my FD.
Ok This has been happening now that I am driving the car more. The idle is weird. If i tap the pedal the idle goes up and then it drops to about 500 and then back up. I hooked up a boost gauge and it is only pulling 16psi of Vac. Is that normal for this engine. Also my oil filler neck has a T for vaccum hoses. I only have the one going down on mine and the side port is opened. I am not sure where it goes.
I have a Apexi power commander computer that is tunned. The car runs fine when you are driving it and giving it gas.
Also when I back up and tap the pedal as I backing up it tends to back fire and then idle goes up and down.
Any idea on what this could be?
OK second issue is that i am not able to get any A/C blowing out of the vents. I checked the fuse and it was fine. What can i check for this issue.

You should post this in the 3rd Gen section:

However, these are the reasons I was suggesting not to buy that car on your original thread....

The A/C fix i will try, but the idle reset using the PFC is a bit too much. My PFC is tunned for stock boost and also has a 16PSI map. Doing the reset will most likely loose the tune.

I have tried the Power FC wire fix for the AC and no luck. I didnt use the same diodes as the directions say so IDK if that is the problem.
When the car is off and your have the ignition open and turn on the AC the AC fan kick on in the front of the car, but not the inside blower.
When the car is on I get an idle fluctuation when i turn the AC on and off. I however dont get the recirculating light nor the AC lights to light up on the AC panel.
Does this mean anything to anyone or where I can find the fix?

I also tried a ground from the red wire to the support brace behind the dash.
When the AC is on and on 1 and 2 fan speed i get the following on my PFC
When I put it on fan speeds 3 and 4 I get the ELD light on the PFC, what ever that means
Also my dash looks like below with no lights or anything turning on for the AC
