Today 02:16 PM
Ralph77 Just the normal stuff like with any XJ.
Except if you care that it might not be OBD II.
Not sure about this but I am under impression that '96's could be either.
Today 02:13 PM
TheBoogieman I'm going tomorrow to check out a 96'. The guy has owned it for 20 years and it has 174,000 miles on it, 4.5" lift with 32x11.50 tires. Any different problems with the 96' and older XJs?

Speaking of, the past couple days I have changed a brake caliper out (pass front locked up driving down the highway) bought the cheapest cb from walmart (cobra citizen 19 or somethin like that, will try to post a pic tomorrow) and I am currently putting dynamat on the trans tunnel to try and keep the heat down in the cab (speaking of anybody got a good place to get the inner shifter boot for a 96 with an ax-15? Mine is about 75% gone)

I have mine mounted to the back on the center console since I have a larger unit. Still allows me to fold the rear seat flat.

Is this what you are doing?
If so what does it entail?
Yes. She was towing an enclosed trailer with the suburban in towing mode and the lifter collapsed. Terrible bit of engineering as the system will fail. Not if but when. For whatever reason when you use towing mode in these gm vehicles it tends to keep the four cylinders deactivated longer and more often. Counter intuitive if you ask me.

Anyway, you have to go in there and figure out which lifter is collapsed and if you are lucky you can unstick it. Either modify your valley pan or replace it with a non-afm valley pan and then reflash the pcm to delete the AFM feature. Those collpasing lifters work on oil pressure to activate. If you have crappy oil pressure, say because you are only running on four cylinders at times and your engine burns oil, they will get stuck and create misfires at minimum and screw your crank up potentially. There is also a tiny mesh filter in the port where the oil flows to those solenoids that clogs if your oil becomes the least bit dirty. It will then starve the solenoids of oil as well.

The "best" way to fix it is to replace the lifters with non-afm lifters and install a new crankshaft. I don't have the coin nor the want to do that as it requires removing the heads. So we are going less invasive and cheaper route of using the existing cam and afm lifters but disabling them through the computer and new valley pan.

It is a pain and after I am done with hers, my Sierra gets the same treatment next. Hers had 156k at failure. Mine is just shy of 110k at the moment and, knock on wood, no issues. I just want to get ahead of it.

$56 for a valley pain from Summit, $35 for a new oil pressure sensor and $50 to re-flash the pcm. Cheap parts-wise but labor intensive.

I have not messed with it yet. It is very marginally longer. If it immediately hit before it, it is now an extra .75 of a second to start. I notice stuff like that though.

Now that I am dd-ing mine I am noticing it is taking a hair longer to actually hit and start.

Now that I am dd-ing mine I am noticing it is taking a hair longer to actually hit and start. Probably need some fresh plugs and a general tune up. Probably about due for some brake pads as well. Until I get wife's suburban put back together she is driving my sierra. I have the top end of her engine torn apart fixing a stuck lifter and doing the AFM delete. Need to get that done but grass is growing like crazy and had to mow after work last night and will again tonight too.
To be frank with you I don't think it does much. Like I said I never really had a problem with it except wishing that there was about 3 inches more of wire to help get it out of the way a little more.
Also when guys first starting doing this they had to make a harness. Plus a bracket for the coil depending on where you were going to put it.
So when I first read about it a long time ago I quickly decided not worth it.
But then Ksuspension came out with the kit. Quick and easy.
On plus side makes diagnosing misfires or determining if you have spark that much easier.
I always kind of wondered how I would figure out if I was getting spark with the coil rail.
Did not research it but guessing a meter would come into play.
Now you can do it like the old days.
Pull the plug, attach the wire, have somebody tap the ignition, and see what you see. LOL.
Also for me cause of the 0331 head I like to keep an eye on things.
Every year as part of my maintenance I pull all the plugs to give them a quick look.
This past winter I had a P0304. Turned out to just be a plug.
But if I had the set up already could have swapped out that much quicker.
Not that it takes that much longer with the coil rail

Can't believe what Tractor Supply wants for it.

With the torque stick in the picture, checking with my HF torque wrench, it works really well.
This is my big boy but only the 700 ft lb, 1100 breakaway one.
Paid $150 for that with a 5.0 battery and the charger.
Picked up that 12.0 for $65 dollars brand new shortly after.
One of these days I am going to find a deal on the 1100 ft lb 1400 breakaway one.
Like I really need one. LOL.
I was looking for a lithium battery model when my Ebay electric one died on me after 20 years. I ended up getting another electric that puts out 1050 ft lbs breakaway. My old one was under 350. I got it at HF during their Xmas sale for $40. It works great, but is heavy at around 10 lbs.
