I used a whole bottle of throttle body cleaner, lots or rags and qtips for the iacv hole. As for the junkyard hoses they all looked in great shape no cracks and not a whole lot of age on them. Thanks for your concern though.

And no, i didnt take any pics. Wasnt even thinking about it.

I heard about that nut and was checked during the cleaning of the throttle body.

 

So how close are we to making it a sticky. How to diagnose the different components, how to replace them, and where to stick the c4 when nothing works.

 

So after reading all 6 pages of this is there a final conclusion? WAS IT THE TPS AFTER ALL?

 

My tps was the issue

 

I have a fix as well...in my case it was the iacv.

If you are stuck on high idle it requires ecm reset or a good used ecm, if you replace IACV it requires ecm reset plain and simple there is no shortcut

 

Tom. No offense. But you are a bit wrong. There is a GEMS 98 Disco 2. And there are many places to read about The use of static iacv settings or even manually adjustable plates in place of the iacv. An ECU reset can be done as well using testbook. Also. I never mentioned replacing the iacv as it still functions in my disco.

 

Here is a archived post from another site from 2008 where a few people are discussing it. I think they are talking about a Rover as well.

Your link is talking about some v6 with a Bosch NOT a rover with gems it makes a huge difference

I take no offense cause I am not going by random posts on sites unrelated to rovers to half *** repair my vehicle then tell others to do the same

Unless you can show different i believe it is generally accepted that D2 production in NAS began 1999 model year
Idle is to be set at 700 rpm
If you have gone into high idle ( limp mode) on a gems equipped ROVER base reference values must be reset in the engine ecu using textbook or similar doing anything else does not fix it

I have run into this 2 times on mine there is no way around it, messing with the IACV as you describe is just screwing the ecm up worse

I will not debate this people can try your way and then still go to a rover shop to have it fixed right

 

I am positive you are wrong about the 98GEMS. I can see my engine.

If you read my post I state that this is a fix if you cannot access testbook to reset your ECU. It is not intended to be a long term fix. And as well I assure you that you are incorrect about it messing up your ecm. Your ecm can run off The values from the other sensors. As well as high idle is not limp mode. Limp mode is a very low idle low operation mode to allow you to drive your vehicle in otherwise undriveable states.

Take a little time to read a post. Do a little note reading on engine operation. And obviously a little more reading on land rovers.

I drive a 1998 Discovery 2 LE p38 GEMS. I can post pictures of the engine if you really believe otherwise.
