when car is in motion and i am aproaching, traffic lights, for instance, i normally knock car out of gear and coast up to lights. the revs now shoot up to over 3000rpm. the only way to bring them down is to stop by using the brakes. also if i lift of the accelerator, cornering & speed cameras the revs do not drop, makes life interesting.
it has had 2 diagnostics carried out by two seperate garages, no error codes coming up.
the, what i think of as the carb, which has a buterfly valve, has been cleaned, and a pipe at the back of the engine, from the manifold to said component, was squshed & worn. it has been replaced. no difference.
any ideas?I have what sounds like the same problem.

I have a ford galaxy with the same problem. took it to the garage and they replaced the idle control valve and it made no difference. I have a ford galaxy with the same problem. took it to the garage and they replaced the idle control valve and it made no difference.

Uuuh... No. There is an electrical link between the brake pedal and the transmission to prevent that from happening.
1. It keeps kids from pulling the lever out of park when they are too small to reach the pedals (first hand experience with that one back in the 60's!).
2. It keeps grownups from pulling it into gear with the engine revved up and crashing into things in parking lots and driveways.
3. Transmissions go from Park to Reverse, Neutral, then Drive. Without the brake on, there would be lots of excessive shocks to the transmission.
P0705 Mitsubishi Description
The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).
When is the code detected?
The transmission range switch detects the selector lever position and sends a signal to the TCM.
The TPS would have been my first suggestion, but, something that can cause similar idle issues is your Oxygen sensor, ( although that generally triggers your check engine light. )
A bad oxygen sensor inables the computer system to determine the proper fuel / air ratio.
You may also have a sensor on the transmission itself that effects the idle, I know some vehicles do, I'm just at a lose for the moment, of the correct name of the part.
I doubt they did anymore damage but i`ll bet that the engine was damaged from the training going out such as valve guides and seals and carbon build up on plugs ETC.
get the car pass on a scanner the check ngine light is probably idle air control valve the first thing to do is get the scanner pass on the car before changing parts for nothing let me now how it turn out thank you and good luck pierre
I will discuss this with my dealer!
Thanks for your interest
