Hi all.
I am been having some idling issues (such as fluctuating idle at lights etc) and I am looking at replacing the idle control valve and maybe the EGR valve as well. My mechanic would like to know if the VX has a idle relearn sequence? Or can you simply replace the parts and not have to worry about such things? :confused:
Any help would be appreciated.

It must home itself on startup, because other than that, all it does it count how many steps out it has taken. The tech manual suggests that you just unplug the old one, check that the length isn't too long, then install a new one.
Yeah EGRmaybe, but I would replace these 2 and then see what you have going on. I would do the EGR next after these 2 were replaced:Quote:

Did you check the OBD2 code reader read out? If not do so, first. Your problem sounds a lot like a code 171. If so, carefully replace the common chamber gaskets. I reco the OEM top, and Fel-Pro brand bottom, about 60 bucks total.

Thanks blacksambo i will check out what we can get over here in Oz that is the eqivalent.
I haven't replaced either of these items, but I've had them both off, & cleaned them with sensor safe throttle body cleaner.Quote:
