I hydrolocked my XJ last weekend. cleaned out everything since. and will be changing out the oil again here in a few days.
the only thing left that is driving me nuts is: it is idling high 2000rpm. If I let the IAC close and then unplug it when the engine is off, I can start it up and it runs fine, drives great. As soon as I plug it back in it opens back up and idles high.
Is the IAC supposed to be all the way open when the engine is running? I can see the IAC move back (pull open) when the engine starts. I have checked everywhere for a vacuum leak, by the mainfold, but when we ripped off my bumper it did pull the vacuum ball out and I also followed those lines with carb cleaner and had no affect.
I think it is the IAC valve, but I would like to hear from someone who knows better than me.
