Microtech LT10 13b Turbo First off I was tuning yesterday and the idle was going up and down tempermently the error came on for map. Im assuming a vacumn leak but my question is if the intercooler pipe leaks would this cause idle to do that. Or is it strictly a vacumn leak in the intake manifold gasket and etc... and yes I've checked all my vacumn connections as well as the map connection.

 

After the throttle body leak is when the idle gets higher. Usually an error comes on than goes away would be the cas,home, just make sure the cas wire us not crossing any power wire.

 

Check for vaccum leak by starting the motor, get a can of cab cleaner and spread around after the throttle body. Don't forget to spray the bottom of the injectors. When the motor idle lower than you'll know where the leak is.


Btw: I'm still trying to figure out the ltx8 you sold me not working out on my fd? I'm using the stock fd cas sensor.

 

Ok just to let you know that oemfd is a fraud, he sold me a microtech which he claim is for an FD but turns out to be flash for a 4 cyclinder motor. Beware of this fraud and scammer!!
