I don't post here much, but this was a head scratcher of a fix that I want to share. A few days ago, my son came home from school with his 98 XJ Classic and sat in the driveway, idling for a few minutes. in a few moments, I heard the sound of the starter grind and then about 3 minutes later...

If you can start it like you did and it ran fine then you shut it off and cannot restart it without flooring it, try cleaning the IAC motor. I would remove the TB, clean it and the IAC, then reset the PCM. Resetting the PCM forces the PCM relearn the correct IAC pintle position. It does this...

The bad thing in your case is that the 231 does have an internal oil pump to keep the bearings and chain lubricated. Aside from the pump running dry and generating metal shavings as it self-destructs internally, all of the bearings ran dry and will also be on the way out (the noise and...

The defrost circuit is on page 8W-48-2. It shows the ground path for the relay going from pin 85 on the relay to the instrument cluster to the defrost switch to ground when the switch is activated. Maybe it worthwhile to check the defrost switch and see if its shorted to ground. If this...

Have a read of page 8N-2. It describes the rear defrost circuit in detail as well as diagnostics. In the description, it says that the instrument cluster is responsible for timing of the activation of the defrost relay. There is a 10 minute time out timer involved and certain defrost switch...

Check your regular mail. Give it a bit of time for all of the files to upload. There should be 9 files there when its done. It should help out a bit.

OMG, what a mess you've got on your hands. Sounds like you've got a few things going on. First, Tim is right on target on the blower motor. High amp draw from a worn out blower motor can cause the electrical harness to melt at the switch...certainly worth a check. With regard to the IOD...

X2 on the black magic setup...works very good. I have them on both my XJ and my TJ and love em. One thing you might want to check before you order anything is to look where your brake pads ride on the steering knuckle. The pads can often wear groves or notches in the soft metal of the knuckle...

Just a note...that does not appear to be lint. It looks more like a mouse has pulled up insulation to make a nest and it has been getting sucked up into the inlet of the blower. It wouldnt be the first time a mouse has tried to set up shop inside a Jeep.

My sons 99 XJ refused to start without giving it throttle. In the end it was simply a dirty IAC. The good thing is that it costs nothing more than some of your time and a can of throttle body cleaner to clean the IAC motor. I like to remove the TPS and MAP sensors as well as the IAC when I...

BTW, did you put the SYE in it or do you know if the 231 had been beefed up when the SYE was put in? I say this because it is possible to upgrade the 231 internals by changing out the planetary to a 6 gear planetary (stock is 3) and adding a wider chain. If the chain is the wider one, you...

One thing I forgot to add is that if the chain has severely stretched and is sagging, there is a possibility that its sagging on top of the oil pump input screen. When this happens, it eats holes in the screen. I doubt this is the case if its got a fresh SYE kit installed, however, if you are...

Get the parts now while you're still able to drive it. You'll need a new chain (common wear item), complete rebuild kit (bearings and seals), small parts kit (has needed spring clips and thrust washers for the planetary) and a tube of ultra grey RTV (love that stuff...makes you look like your...

Yup...somewhere between 15 to 45 seconds on a cold engine. If he has the problem immediately from a cold engine start, its not likely o2 sensors playing into it...also why I said it would be helpful to have a scanner to verify what mode his is in.

Forgot to add... I was taught to always replace the pushrods, lifters and rocker arms when going in with a new head. If you consider the wear of valve train components wearing as "a set", this is logical advice. You dont HAVE to swap in new pushrods and lifters but it might be foolish not to...
