HELP, 16 codes on 2002 disco2
Hello Everyone,
New Member / long time follower with a desperate need for advice. As short as I can here is my situation:
Truck was running poorly (smelly exhaust, rough idling and a banging noise) so took it to mechanic specializing in Land Rovers. Report was, truck needed new head gaskets, MAF and O2 sensors and was showing 14 trouble codes. After repairs, they would then determine if I needed new catalytic converters. Estimated cost was well above the value of the vehicle so I took on the project myself with parts ordered online. After removing heads, there was no difference in the appearance of any of the cylinders. I took heads in for cleaning, testing and machining with a good result. After reassembly, truck seemed to run fine in driveway until I took it around block and barely made it home. I had no problems with the work I did and since truck drives very similar to just before I took it apart, I think problem is unrelated to head gasket problem. As of today, I am showing the following codes P1884,P0303, P0305, P0307, P0301,P0300,P1300,P0155,P0135,P0134,P0154,P1590,P0 340,P0448,P0445,P0102. P0301-7 say misfire on all drivers side cylinders, so I disconnect a lead and tested for spark with one of the old plugs (replaced all plugs with new during head job) thinking maybe I had a bad coil pack. Spark was strong. Thinking I can't have almost every sensor fail at the same time, I went looking for a bad fuse and found the 15A engine management fuse blown in fuse box adjacent the battery. I replaced the fuse and no difference other than engine now faulters when I disconnected connection to MAF sensor (it didn't make any diffence earlier.) The banging noise turned out to be the heat shield on the drivers side catalytic converter had a broken weld which I repaired. I have not yet replaced the 02 sensors, but did clean them up prior to reinstalling (lots of accumulated soot). During my repairs, I cleaned the fuel injectors in an ultrasonic cleaner and replaced the seals (kept each injector in original place as I was not sure if it mattered). Exhaust is STINKY and leaves a sooty black stain on driveway until warmed up. Its now too dark to continue and I need a mental break - its gotten personal now! Any advice is welcomed. Thank you!!!!!
