Looking for a Disco II Specialist in NJ/PA/NY
I am in need of someone who can sort out a couple electrical bugs in my D2. I decided to put the truck back on the road, but I have a couple of electrical bugs I need sorted out. Cannot for the life of me get the upstream Oxygen sensors to work. Codes P0135 and P0155 for the heater circuits. Small air circulation fan next to the steering column will not go off. Even if take the keys out of the Truck. Sometimes the HVAC head unit stays on, even after you remove the keys, and I'm still trying to figure out some EVAP issues. I have fixed everything else. I need to get the ECU to show clear on the OBD port or it will not pass New Jersey state inspection.
I am located in southern NJ, close to Philadelphia, and I work in northern NJ, close to NY. I could go either direction for the right mechanic. Is there anyone in the midlantic area who specializes in working on these trucks, particularly the electrical and or emissions systems. I'd really love to start driving this thing again. I really miss it. I've finally gotten all the mechanical issues straightened out, It runs incredibly strong, handles nicely, and brakes perfectly straight.I just can't get it to pass an emissions test.

Just wanted to give you all a heads up. I usually try to loop back and update a thread if I am successful fixing any of the issues that you all give me advice on. This time I managed to solve a few of them all at once. ( This is a long read )
Rather than taking this to a shop, I figured it was time to buckle down and see if I can make some head way on my own. Just over a year ago I spliced in as section of passenger side O2 wiring. The wiring had melted through on the ex manifold, it shorted the wiring all the way up behind the intake manifold, and I was getting O2 codes. I had a coil go bad, and I was getting misfire codes as well. So while I had the manifold off to get to the O2 wiring, I replaced the coils and plug wires. Put it all back together and I still had the O2 codes. Misfire codes were gone, but still had the O2 codes, and it would not pass five of the eight emissions readiness checks. Completely disgusted, I just shut the hood and walked away. Did not touch it for a year.
Fast forward to last month. I got tired of looking at the Rover sitting in the driveway and figure I needed to do something. Looking at the O2's, I could see that the passenger O2 connector was a bit buggered up. Must have melted along with the under hood wiring, and I never even noticed it. Ok, I'll replace the upstream O2's again, and see what happens. O2's will not come out. Not all all. Not even with the O2 tool, heat, PB blaster and an impact gun. I had already snapped two O2's in one side of the Y pipe, and one in the other. Already had three new ports welded in, and the cats were at 145K.
At this point I just said **** it. I bought the entire manifold back exhaust system from Magnaflow. New cats, new Y pipe, new muffler, new everything. I was tired of messing with rusted old exhaust parts. I also bought four brand new NTK O2 sensors. They were not cheap, but everything I could find reading up on them lead me to believe they were the best option.
Dropping out the old exhaust, I managed to snap four studs in the exhaust manifold. Then I rounded one of the 12 point exhaust manifold bolts trying to get the manifold out to fix the broken studs. Drilled and re-tapped the manifold for the one stud. Drilled all the way through and used stainless nuts and bolts for the other three. Cut the head off the one manifold bolt. Ran a die over the threads and used it as a stud. I was not about to risk snapping it flush with the cylinder head. It worked fine as a stud, I just left the spacer off.
Next up was the install of the Magnaflow system, new gaskets, and the O2's. I cannot speak more highly of the quality of the Magnaflow product. Full stainless, mandrel bends, slip connections, and bolts right in. The fit and finish are fantastic. Everything went into place effortlessly, and exactly where the OEM system had been. Kudos to Magnaflow. Again, not cheap, but worth every penny. Screw in the new NTK O2 sensors, connect all the wring.
Fire it up. It smoke like a SOB, but it seems as though it's just burning off, and getting the Cats heated. Let it run for about a half an hour at various RPM's. NO CODES!!! No O2 codes, no misfire codes, nothing. first time in four years that everything worked. Put it back on the insurance on Tuesday, and drove it to work on Wednesday. By the time I got home from work on Wednesday, it had passed all eight readiness checks. First time for that since 2014. Truck sounds amazing. The Magnaflow system is perfect. Not too loud, but a nice V8 growl. The truck runs the best it ever has since I've owned it. I had used Bosch O2's in the past, and it was a constant battle to keep them working right. I replaced the coils with the Bosch units, and put in Magnecore wires. I changed the oil and flushed/filled as much of the antifreeze as I could. I forgot how much I enjoyed driving this Truck. It definitely pulls harder than it has in all the time I've owned it. I cannot recommend the parts listed above any more highly. I am convinced that is the reason that I have finally gotten this rig to where it will waltz through NJ state emissions inspection. My plan is to make a sort of overland/beach cruiser hybrid. I'll try to get some pics posted when I get a chance. And I'll make sure to keep posting as I get this truck to where I really want it for offroading.
I really want to thank all of you for you contribution to this forum. I did not6 post a lot of questions directly, but I have spent hours searching through your posts t get the answers I needed. Thanks for all your help. This was a really good week.

Total for the Magnaflow system is right around $1300. It’s pricey, but the quality is better than OE and sounds amazing. Everything just bolted into place, right on the factory hangers. And since the Y pipe is two piece, you don’t even have to drop the cross member. For me, it’s well worth what I paid for it.
