Hi Drivers

I need help with my evo 9, something is wrong with my "baby". Yesterday I drove to work and park the car as usual (here comes the knightmare at least for me). after work when I started the car The RPM was up to 3000 and won't come down even after warm up; and today the same thing. I looked arround and everything seems to be in its place and all plugs connected, I don't know if Iam missing something it happened out of nowhere.

HELP please.

 

Mods? Check the throttle cable if it is stuck or adjust it. Also you can lower the idle on the throttle body.

 

Check to see if something is blocking the throttle plate from closing. Pull the upper intercooler pipe off at the throttle body and check...

 

vaccum leak...

 

Cheked the throtle nothing is stuked there. There is also no vacum leak. Could it be the TPS?????

 

Drive it to the dealership, if u aren't modded, get there soon for warranty work.

 

recheck to make sure all the plugs are in
especially the one on the left side of the intake manifold

 

Check and make sure your floormat didnt hike up...

 

I still can't find the problem; Guess I have to go to the dealer for a warranty check...

 

Have you messed with anything latley? Where the throttle cable mounts to the bracket behind the valve cover if those botls are messed with you can tighten the cable which in turn will hold the butterfly in the TB open causing your idle to be high like that

 

I remember my VR4 Galant idling at 3000 rpms becuase a bad TPS I dunno if its the same on the evo.

 

I was wondering if this could be caused by the EGR; if so where is it located?

 

drive to the dealership have them diagnose the problem, might be somthing to do with your Maf, if you still are stock not modded go to the dealership and have them take a look at it.

 

SORRY!!!

Iam just desperate i havent been able to drive my car for a few days.....anyway I think is a good advice

 

It's got to be a vacuum leak.
