Well my idle was beeing really wierd latley, it would shoot up to 2300 rpms on cold, and then sit at 1900, then go down to 1500 till warmish then down to 900 in drive. So i cleaned the IAC valve and it was pretty gross, it make it idle better, now, when hot you start it and the RPMs shoot way up to 2500 rpms then quickly go down to 1300 then creep down to 900 and then idles a bit rough. Same with cold except it stays at 1500 untill warm then goes down to 900. What does this sound like?

Install that and then we will talk :wink:
get a new crossover and it will fix a lot of your issues. that think spilling exhaust into the engine bay is a huge problem for driveability.

Haha, my K&N is coming today! But i need a tune up before i do that dont I?
Most of your problems are caused by lack of normal maintenance.
Do a complete tune-up and fix the crossover leak then see what kind
of problems you have have.
If you spent as much time on your car as you did on the computer
complaining about your car, you would be a lot farther ahead...
I dont have a job yet ,im trying to get one, its hard in a small town. I dont have $525 + $300 for a Rebuild on my turbo scince its coming out anyway, so no i cant do my cross over any time soon
When you cleaned the IAC and replaced it did you do an idle re-learn?
In the chip it will set the IAC steps to a certain open value for initial start-up idle. If the pintle was moved during your cleaning and the IAC does not know where it is relative to the last time it was shut-off prior to your cleaning it may be thinking it is a 90 steps but actually it was moved and it is at 130 steps but still thinking it is at 90. Now you say it drops the idle...drops again and then levels out right? That will tell you you have an operating IAC...but most likely it is confused at to where it is. Pull the ECM fuse...let it sit for an hour or two...put the fuse back in and do an idle re-learn.
Now if you have a cracked x-over, bad plugs and/or wires, clogged or shorted injectors, and/or other faulty components under the hood it WILL NOT run properly till they are taken car of. You need to realize that especially a bad x-over will cause extremely erratic running conditions which will easily lead to a dead 02 sensor, fouled plugs, and a number of other things.
By no means am I telling you to give up...but there are many maintenance related items these cars need to keep them in "good" running shape. Seriously though...you need to stop whining about your car. :wink: 8)
well i installed my Free195 today, it idles alot better, but not as good as it should, thanks for the suggestions TGPilot, ill keep those in mind!
So, since it was mentioned. What is the proper procedure for a good idle relearn?
The way I have always done it...and I think it is close enough to the tech manual.
1). Make sure engine is cold to start this procedure.
2). Remove the ECM fuse (located under the fuel pump relay cover) for about 5 minutes. Some will reset immediately some have some capacitors that like to hold on longer so 5 minutes is a good rule of thumb. This will force the IAC to find it's home or proper step position.
3). Replace the ECM fuse and start the car.
4). Allow car to idle until the main fan (Radiator Puller Fan) turns on, then off, then back on. Once it has cycled through the last time and turned off....turn the motor off (not a good idea to turn off a motor at peak temp!). When you restart the IAC should be in proper home step position and ready to control properly depending on what temp is sensed in the Chip Values by the ECM.
Some will rush the process by putting the tranny in gear and power breaking the car to generate heat faster. You can do that but the IAC steps will change as you do this to "follow" the throttle. Does it effect the process...I do not know...but if you just take your time and let it do it's job you are much better off in my opinion! ;) 8)
I want to say that you are supposed to leave the car in drive, either keep it in position by chucking one of the front wheels or use the e-brake to hold it in place while the car warms up to temp. I will consult my manual for proper idle learn procedures today. It's almost 60* here and I'm gonna test this new mastach cable of mine. :o :D
Probably. I do not have the manual in front of me...but that is to help it run up to operating temp quicker. I suppose that is a good idea as long as you do not touch the gas pedal. The IAC counts will follow the throttle and throw off what it is trying to find as proper positioning. 8)
