Hello all, I have a 96 discovery 1 that I have been daily driving for a little over a year. A few weeks ago the truck started to limit rev around 2000k. It does it while cold or warm in gear moving as well as stopped in park. Truck runs fine at idle, can still be driven up to about 50 mph but stinks like gas real bad. Plugs and wires are less than a year old and wires were quality. Just changed coils because they showed signs of heat. Holds good fuel Pressure and vacuum. Still tested for leaks with nothing changing. Only code it currently throws occasionally is a random misfire. I changed the MAF no difference. I pulled my cats down thinking they were plugged, open manifold it still limits around 2k rpm. I took it to a reputable master rover tech near me that has helped me out in the past. He plugged into it and we drove it around everything checked out electronically. He suggested plugging in another ecu, so I picked one up and plugged it in today and my problem still remains. I have a new set of Bosh 4 hole injectors I plan to put in it today.
Any thoughts or assistance would be much appreciated.
