GadgetmanNebraska here with another groove on a great car.

John Tramner brought me his 2005 Impala to be grooved on January 2nd.

This groove is farely easy and all I do is reduce the size of idle air hole by 1/2.

You will notice that the idle air hole is square. All I do is cur another gasket and

make the square 1/4 the size of the original hole. You will notice that the car will

start right when turn the key after doing this modification.

The test drive went very well, as John noticed the engine running much quieter and

the transmission shifting much better also.

He will probably be contacting me for the mileage soon. HAPPY GROOVING
