HELP. I screwed up!

I replaced the spark plug wires on my 2000 Discovery. I THOUGHT I was REAL careful in replacing the right wire to the right connector BUT apparently the way my truck is running I'd say I screwed up somewhere. I checked the owners manual and it has a picture that makes NO sense.

It has 8 connections straight across. My connections are 4 top 4 bottom..

AND is there an easy way to connect/ disconnect these wires other then climbing into the engine compartment? They connect behind the engine, and face the firewall..

ANY help would be greatly appreciated at this point.. I would drive it to a garage for them to fix my bonehead move, but am afraid I would REALLY screw up the engine then..

I can't help you with this specific situation, but I'm sure someone on here can. But, I just did the same thing on our 90. I turned it on and immediately knew I had done something wrong. Luckily, I shut it off quickly and checked the wires with those off of our disco (94). I found I had crossed cylinders 2 and 3. I switched them back so they matched the discovery's and everything is working fine now. I think I got really lucky and nothing permanent happened. Maybe someone on here could describe how theirs is set up and you can double check yours that way. Or better yet, if you could find someone near you, you could check it right there.

I too looked and looked in the manual for a place that talked about it and couldn't find it. Luckily we had the disco with the same engine to compare.

Good luck with it mate.

Well, not to rub it in but it sounds like you learned a lesson. When replacing wires, remove and replace one at a time. Pull one off, match it up to the one of similar length (new wire set) and replace. I believe the area you referred to as having " 8 connections straight across" is probably the coil pack which in my 97 D1 is mounted near the fire wall. Not too sure if the D1 and D2 are similar. Hopefully another D-Weber with a D2 will chime in. If all else fails I can take a look under the D1 and try to sort things out for you.

Let me know,

Bob,
Just stuck my head under the hood of my D1. My coil pack is a straight series of 8. They are mounted to a bracket that identifes each of their locations.
Reading from the drivers side to the passengers side they are 1,6,5,8,7,4,3,2. These should be connected to the cylinder firing order (2,4,6,8 on passenger side, 1,3,5,7 on drivers side ...with 1 and 2 cylinders being the closest cylinders to the radiator. Hope this help.

I wouldn't worry

I wouldn't worry about any damage done by mixing up the plug wires... I've done it plenty of times on my other cars. It's just firing at the way wrong time, causing backfires, or crappy running, or no starting. Mixing up 2 wires on a V8 will usually just mean running with two less cylinders firing right... I wouldn't drive the car this way of course, but she'll be just fine. ;)

how long.....

does it take to remove the upper inlet manifold assembly so I can get to the ignition coils?

I have heard it is possible to stick you hands back there but ..... just wondering.

On a D2 you could do it if you had the hands of a 2 year old child. It was not possible for this full grown adult.

Hey Bob -
How long did the whole process take and did you have to remove the upper inlet manifold assembly?

Sounds like there are some who can do it with the assembly on and some who can't. I'm getting ready to do this on Saturday.

Thanks in advance.

I wouldn't remove the intake plennum if you don't have too. I was able to change out the wires without dissasembly. It is however, difficult to change one wire at a time without dissassembly. If you take all the wire off make sure you draw a diagram for yourself that you understand and make sure to replace wires with new equal lenght wires. Also, if you do take off the plenum there is a gasket that if your not careful, you will have to replace (on a D2). Good luck and learn to suck up the knuckle bruises :D

jmonsrvr ,
My 97 D1 "coil packs" are of an in-line eight variety and are mounted to a bracket which has their "order" stamped into the housing. This bracket is either mounted to the fire wall or to the back ends of the engine/manifold. I just scrapped off the crud to expose the stamped markings.

Hope this helps clarify

A clarification to my previous reply to jmonsrvr

There is no identification on the bracket that "identifies the location of each wire....from cap to engine" but rather it identifies the location of the coil pack "number" (1 thru 8). Knowing this and the firing order, all you have to do is match them up. Coil pack #1 goes to cylinder #1, coil pack #2 goes to cylinder #2 and so on.

On my 87 RR is much simplier, no "coil pack" just the conventional Lucas coil and distributor cap.
