Never done this before (idle issue)
 

Today when i started my car to go to work it idled at 1500 rpms and stayed there for about 3-4 min then all of a sudden just went to normal. Now when i stop anytime the car sits at 1500rpms longer than it used to and goes down to normal. Its never taken the car this long ever to find its idle, its kind of strange. I have some non-platiunm plugs that i'm going to try that i've always had as back up and also an oil change. I'm confused as why all of a sudden the car idles like this.

Mine does the exact same thing, I dont think it effects anything. However mine started to do that AFTER i had the fuel hose recall done where seemingly everything is ripped apart and put back together.

My AWS is also screwed up now. When you start your FD, it is supposed to immediately jump to 3000rpm for about 10 seconds, then kick back down to 1.5k and then to 750-900 after warm. This Accellerated Warmup System should kick in everyday when you start the car, it will not however kick in if lets say you run your car an hour, park 4, then start it again.

Again, the AWS not working correclty, well, I am gonna just let that one go, sometimes when i start it starts off at 1500, then goes to 2500, then 2000, then 3000 all within 7 seconds or so, then kicks back down to 1500. Strange and I cant narrow it down.

Other idle issue is when I let it sit after start, at the point where the car is warm and settling around 1000rpm, it goes up to 1250 and back down to 1000, and repeats that exactly 5 times,, then you hear the motor kick sound, (same one when aws shuts off at 3000rpm) and it settles at 750rpm.

This stuff is enough to drive you crazy, so I am not gonna worry about it too much, my car runs great. I would rather have the weird idle problem, then have them rip the entire thing apart again, fixing one thing and potentially breaking 4 more.

I don't have AWS anymore with my powerfc.

I just don't understand why when i'm coming to a stop it sits around 1500 for a few then finally finds its good idle. My vaccum is good, and when it finds the idle it idles good too.

Well i just started the car and it idled at 1300-1600 rpms the car was cold but it idled there for awhile and i just turned it off.

It was something simple thank god. It always seems to be something simple.
Well i started looking around at the vaccum lines that i have left since going single and the one from UIM to the oilfiller neck had a split right before the nipple. I replaced the line and now idles back to normal.
