Hello everyone,

I would like to request some experiences from you... I just installed a Mr.Josh lightened (not underdriven) crank pulley on my 05 RS Wagon and now my car idles at 400 RPMs. The revs quickly jump when i hit the throttle but I am a bit worried about this slow idle. the only other engine mod that I have is a short ram intake. Please someone assure me that all is good so i can sleep again...

Thanks,
Jason.

 

Reset your ECM. Pull the negative side cable from the battery for a minute or so... pump brakes a couple of times. Put cable back on battery. Start it and let it idle till warm. Drive the wheels off it ~ you should be golden!

If it's warm where you are. Start it with the AC on ~ the idle will account for the compressor being on.

 

my mistake; I disconnected the positive before the install; could that be the "issue"?

 

That will correct the issue. The ECM will find it's old idle speed and reset for you.
