Hi all,
I have just replaced the camshaft on my 1993 EFI 3.5 V8 discovery. During this I have completely stripped down and cleaned up the plenum also. After rebuilding, I have started up for the first time and the revs surge up to 3k + revs immediately after starting up. Sometimes the revs will jump to 3k, sometimes 4k and once or twice 2.5k. They do not settle down to a normal idle. I have checked that the throttle is not open. I also have a red temp warning lamp on immediately on start up despite cold engine.
