Deb brought me her Ford 1997 f-150 pick-up with a 4.2 V-6 engine. When she started the vehicle she had to hold down the foot pedal to keep it running. She told me it ran very sluggish and would not go into overdrive when passing someone. I did the groove on her truck, and she was surprised that she no longer needed to hold the pedal down. Deb also commented that it now sounds like a race car. To hear her testimony please go to my GadgetmanNebraska youtube videos link (sweety95194) to hear more about her experience with the groove

Be sure you reduce the size of the Idle Air Pathway to give her the gains she so richly deserves!
