Hi all, was trying to be a good brother today doing a major service and repairing the cracked exhaust manifold on my sisters 99XJ. Repairing the exhaust manifold obviously entails taking of the inlet manifold, unplugging all the wires, fuel line off the fuel rail etc. Everything went back together ok but when I fired it up, the engine raced to max revs instantly, pretty sure it would rev till blew up from the sound of it if I didn't switch it off. I can't understand how it could do this, particularly since the throttle butterfly does not open at all. I tried resetting the computer, no luck, I'm out of ideas at the moment other than towing it to the nearest Jeep dealer, Any idea's anyone???
