Sticky Accelerator

I have been having a strange problem where the accelerator was not releasing and the engine would continue to race and the RPM shoot up to 2000 - 3000rpm whenever the clutch was pressed or when in Neutral.

Yesterday this problem really came to a head and it was a real dangerous experience getting my son safely to school!

Options:

* The Engine Computer has gone mad
* The fuel line is stuck
* The accelerator pedal is catching in the floor mat
* Dirty fuel has blocked something in the fuel line


However today I found out what the problem really is:




The Air Inlet Manifold unit is made of plastic. The flange that attached the unit to the engine body was broken. This allowed the inlet manifold unit to rotate a few degrees clockwise. This resulted in the butterfly valve axis being off so when the accelerator wire pulls and rotates the valve it was not able to go back to idle position.

I had a similar problem.

It got fixed on my second visit to the workshop for the same problem.



However in my case it was only lubrication of the cable and the pedal that solved the problem.

I bet this is also a problem due to moving the driving seat from Left to Right

Glad to announce: Intake manifold assembly replaced under Extended Warranty.

In their air intake design they have separate throttle body which has to be seated properly and this body is held in place with the air filter box. It is important that air filter box is properly tightened.

I faced similar problem after some days of getting my car serviced. I saw that the air filter box was loose and not properly tightened. On removing the box, the throttle body was not in its proper place.

There was a marked difference in acceleration after proper seating and tightening.

Although removing only top cover gives access to air filter, surely these people at mahindra service must be removing the whole air filter body to clean the air filter and not doing a proper job of re-fitment. There cannot be any other explanation, it is bad work on part of mahindra service/dealer.
