i installed a plemun and 75mm throttle body. when i started up the engine it stayed at 2,000 rpm then went to 3500 rpm.. what could cause that problem. is there ne way to solve it. could it be the tps? or would there be something wrong with the instlation.

 

Could be the install. Double check yourself

 

can't you manually set the idle? just turn the screw

 

vacuum leak

 

Did you disconnect the battery for 5-7 minutes to reset the KAM? The Keep Alive Memory is where learned values such as idle air and short an long term fuel trims are storedany time you mess with intake or fuel system components you should reset the KAM...

 

ya when i first installed it i disconnected the battery.
