Moosa-

I got your PM and responded. Reading this however, I'm going to venture and agree with the VSS being the culprit. You'll need to double check that it is plugged in and didn't somehow get damaged in the clutch swap. (Trust me, it happens more than you think).

Good Luck!

thanks a million guys for your response and support in this matter


but i still cannot see how my vehicle speed sensor has any relation to drivability??

 

also..a quick question...will i be able to access the vehicle speed sensor from the engine bay or would i need to go under the car?

 

According to the FSM if I'm looking at the picture correctly, it sits right on top of the bell housing.

yeah..Mr DTUNED was kind enough to email me a diagram showing me where the vss sits..however am at work and away from the evo so i was wondering if i could access it from top...looking at it now..i believe i can!!

thanks guys..will give it a try at home and report back!

 

Moosa, I emailed you the links for the EVO IX work shop manual and the 05-3 supplements. Download and keep those. They are worth more than gold.

The VSS is associated with the car's speedo (erroneous speeds or ceases to function) and can affect the rev limiter by decreasing it if it is bad or disconnected. A bad VSS can also affect the ABS system. I am not certain, but I am inclined to believe that the EMS will also take a sample from the VSS in order to calculate/refine the air/fuel mix, hence the weird symptoms you are experiencing at idle. Someone check my math on this.

 

i agree with your dtuned in all except one...i dont believe my VSS could be disconnected because i am getting speedo reading and my odo is increasing normally....i will check it however and report back...

<------confused :S

 

hmmm.. i woke up this morning with the craziest idea in my head...i think in my head i have found the problem...its the low voltage at the off throttle thats causing this issue..

i have been having a problem with my battery anyways..so i am going to switch from this battery to a new one!

 

That'll do it. make sure the terminal contacts are free of corrosion and the regulator on the positive side is connected firmly and is free of corrosion, as well. If you have corroded terminals, you will have current leaks and low voltage indication. GL. broham.

 

so what was it Moose?
