Question Throttle response ??

I have a "new to me" 97 supercab 4x4 with 140,000 miles.
How far is normal to push the throttle pedal before something happens? I can mash mine about 3/8 of an inch(feels like an inch) before the engine changes rpm's. Also hear a click (micro switch) at about the same distance.
My company's f550 6.0 has no dead spot .... touch it and it throttles up

Do I maybe have a bad throttle switch???? or is that a 97

That is normal for OBS trucks. The newer ones have a little different pedal configuration.

You can take the pedal out and tweak the microswitch to get most of that play out if you want to.

Accelerator Adjustment
In some cases, the accelerator sensor doesn't respond as it should. You may notice it clicking or hesitating when you push on it. The accelerator on the Power Stroke is completely electronic, there is no throttle cable. This sensor can be adjusted for better throttle response. Go easy though, if you adjust it too far, you may have a problem with the engine resetting to idle. There is no adjustment on the switch. I had to bend the tab on the accelerator that depresses the switch until I was satisfied. WHAT A DIFFERENCE!!! It's nice to have throttle control.
