greetings all,
i changed the spark plugs on a greddy eqiped g35 today. went 1 stage colder. when we restarted the car, it died. when we started it again, it died. we did this about 5 times until we realized that if we blipped the throttle once, very slightly before it died it would idle fine.

has anyone heard of this problem? is this related to the new plugs, or could this have been from disconnecting the battery? does the emanage have to be reprogrammed, or reset? it was like we needed to tell the computer to raise the idle.

it is definitely not a vacuum leak, because after we blipped the throttle it would idle just fine.


any info would be great.

Thanks!!

 

I installed 2 step colder but at the time of TT install and all went fine not starting problems.

The emanage should not have to be reset afte the battery is disconnected, you might want to do the ECU and throttle resets and see if that helps.
