Hello everyone, it's been awhile since I've been on the boards, but I've got a recent development I could use a bit of help with. I recently bought a Mazda Miata so I haven't been driving the trooper as much as usual, however recently the truck has started to develop what I would call a stutter while cruising down the freeway. It's not a misfire as far as I can tell, it's like I'm playing with the gas pedal. I have no idea on whether it could be something like the TPS, or even the transmission itself (Automatic Trans). I did recently disconnect the Power/Normal button as it broke, could this possibly cause the issue?

It's late, but I'll try to get a better diagnosis tomorrow afternoon.

Thank you for any help you can provide,
- Jim
