Ok I got codes.

P0305 - P0308 for misfires in random cylinders, autozone guy said cyliners 5 and 8.

Also, got code P1688 which he listed as a (general motors ?) Fault for Generator L terminal control circuit.

Got my plat +4 plugs and 8 mm wires today.

Thanks again all for the continuing help.

I decided to purchase replacement coil packs as well since I am going to be in the area anyways. Read the sticky on changing wires without removing IM , is tha also applicable to changing out coil packs as well? Just wanted to make sure I could get to both.thanks again all

Why new coils? Nope, I doubt you'll get the coils out without pulling the upper intake.
I can't even find and have never heard of a 1688 fault code for a Rover.

 

Well new coils because guy at columbia rovers said it was prob that. I will install just plugs and wires first, you don't sound convinced it would be coils so I will hold off. Mike thanks for info.

If they tell you to replace the rear bumper also, Don't.
I have 30 years on the books in the service departments and you have no indication of a coil failure, they want to make some money off you.

 

That seems like waste of money and time, you will need to take off the upper intake manifold to get them out.

 

UPDATE:

8mm Wires and +4 Plat plugs in. My Disco Runs Great again. While I had off all the intake hoses I also followed the sticky for cleaning out the throttle body. That sucker was DIRTY!

Everything is cool now, no more service engine light. Disco Mike, Thanks for saving me a couple hundred bucks and having to remove my IM!

for everyone else out there reading, Stickies for plug change w/o IM removal and TB cleaning work GREAT, thanks to the owners of those stickies!

Later

Now, consider doing an induction cleaning and with your next oil change, do a ATF engine flush, both will improve things even more.

 

Yeah the induction cleaning and a can of seafoam in the tank did wonders definitely do it. Glad you got things running well again. Keep up with the maintenance on these things or they will start to fall apart fast.
