Hey well I just picked the D1 up from Rover Cannibal and the new pump is installed..However @ idle in all gears the engine is running @ 2300 -2400 RPM's..There is no check engine light yet no pd codes ..and @ first I thought it was the throttle cable was too tight ..thats not it @ all.. It acts like someone is holding down the gas pedal...from inside the truck ...Any thoughts. The shop has closed for the night .. here we go again. It never did this before the "new" pump if that helps.. The engine is RACING and the car is in Park...
Really high idle

Try disconnecting the Battery for a about 10 minutes and see if that clears the memory and fixes the issue.

And it was at CarCannibal.. ahemm...
Do you still have original stepper motor? Did you check throttle plate? Do you still have original MAF sensor?
Check if someone forgot something inside your airbox. High rpms can be there also b/c air is too restricted..

Fast idle, & other tests
Rover Chick, check all vacuum lines,pulled off, loose or cracked. Remove the stepper motor and watch the plunger at the same time have someone start the engine, with the hole in the airbox open you should have a high idle and the plunger extend.
This is a check for the stepper motor to see if it's functioning, with motor off and ignition on the plunger should retract. Go to plan B, take it back to the people who replaced the pump.

Serg I just checked all of the above.. Everything is what was on the truck to begin with (just checked the MAFS ~ I marked it with my name and its still there ~ I also checked that is my stepper motor too) .. It has NEVER done this before... I still have the battery disconnected now..In Idle the rover is sitting @ 2500 RPM?? It should rev in idle @ 700 plus or minus 28 ...I have had it I am calling the Atty General.
I was @ there mercy... It was there or the dealership ...

That sounds like the Idle control setting in the ECU....someone correct me if I am wrong....needs set with the Testbook.

lol melissa you are one nutty lady!! lol wait for something else to happen once idle goes back to normal. 
just kidding 
just kidding Its Not Good
Its not good.....Just back from the shop ..They said something about the thermal switch?? And that there was something wrong with the the idle circuit but they do not know what?? Help ... All of the sensors have been checked and they are all *ok*(ohms) ...VSS, TPS, MAFS.. No check engine... Here again are the problems ~ in N and D only the rover will REV to about 1200rpm?? Only in these gears will it rev this high... Why do I have some weird feeling this *is* the ECU.. WHY ME???
If I run the a/c it helps a bit as far as the rpms go... Is there a way to test the ECU?
