Hi guys I still have my 1997 2.5 TL.
I've been having a rough idle so I sprayed intake cleaner into the port to clean it out. The little door was sticky around the edges.
I did not remove it from the intake manifold but I did disconnect the negative battery terminal.
After letting it drain and evaporate it started up fine.

Now though when it reaches operating temperature, once I let off the accelerator, it idles very low and stalls. I have to hit the gas to prevent it from stalling.
Once the temp is low the idle is fine and it does not stall.

I also tried removing the negative terminal again for 5 minutes to see if that would make a difference. I read something about resetting the ECU that way.
No luck it still stalls.

Did I ruin something by not removing the intake first?
I'm annoyed at myself. It was idling rough before but at least I could drive.
Any ideas?

One more thing. Initially the first time I tried to start after cleaning it would not start, but I thought that I just didn't give it enough time.
I tried again after 15 minutes and it started fine.

I turned the idle screw up a little and now it stays at ~750 rpms. It's not stalling.
Peace guys.

Next I will remove the IACV and clean it separately because it probably sucked some gunk that came off from cleaning the port door.

My guess is that some of the gunk clogged the screen on the IACV, and now it cant pass enough air to idle on its own.
