I was talking to a known mustang guy, and he said that some mustang guys who made changes to there cars, and have idle problems say by adding a small hole in the butterflys of the TB will smooth out the idle.

Kind of makes sense don't it? Has anybody ever tried this on a third gen? I'm thinking about trying this since I plan on buying a bigger TB in the near future. Let me get some feed back. Thanks

 

That was an old carb trick. You did it so there wasn't a pull on the fuel circuit that you would get if you opened the blades more. On a Throttle Body, just crank it open slightly more. You will need to re-adjust your Throttle Position Sensor, but you knew that.....
