Howdy,
I’m new on the block. I’ve been messing around with the search function all day, but can’t quite find the answer to my question, so here I am!
My wife and I just purchased a 1998 Disco 1 (both of our first experience with Land Rovers!) with 122k as a toy/over landing project. It’s a runner, or so we thought, and our plan was to treat it as a third car/winter car while we slowly turned it into the adventure-rig we’re looking for. We drove it around for a couple hours the first day we got it, took it to go hiking, ran some errands, all without issue, until we went to the grocery store. Having left it for twenty minutes we came back to the rig, loaded up, fired up, only to have it surge, stumble, and quit immediately. Subsequent attempts to start lead to the same result. It would crank, catch, idle, run rough, lose RPM, and die. Good. Hood up, wife in the driver’s seat, me up front, I could occasionally keep it running by blipping the throttle, but only for a few moments. I did notice, however, that there seemed to be a “hissing” sound, like a vacuum leak, towards the left side of the engine bay. Couldn’t locate it though. Kept having the wife attempt to restart at intervals, hoping to find the leak. Couldn’t. Same stuff. Loses RPM, runs rough, misses, and dies. At my wits end, and purely on a hunch, I disconnected the intake from the air filter. (Did NOT disconnect any wires, however!) What do you know? Truck starts right up and idles away happily like it hasn’t a care in the world. More concerned about getting home than looking a gift horse in the mouth, I push all the guts under the hood, leave the air box disconnected, put my wife in the passenger seat, and drive home... without so much as a hiccup. Safe in the driveway, and without shutting down, I reconnect the air box - no problem. Truck idles away happily. I check the filter - it’s clear. Check the air box inlet - it’s clear. Still a hissing from somewhere in the top left of the engine bay. I’m starting to think my air box disconnect trick has nothing to do with the restart.
Any ideas what I’m dealing with here? I’m figuring I have a vacuum leak somewhere that is messing with the fueling on startup. I’m inclined to just start replacing vacuum hoses. Am I on a goose chase?
Good news - the wife loves the truck and I can keep it. Bad news - she’s named it, and so I HAVE to keep it. Help!
