I have a 97 Wrangler 4cyl manual with 150k miles that has just started sputtering when I hit 30mph. It didn't start doing this until I replaced the power steering pressure switch that was causing the check engine light to come on. After replacing the switch, I disconnected the battery to reset the check engine light. After that, it sputters and stalls starting at 30mph. If I floor it past 30mph, it trys to sputter as soon as I let off the gas. I have no idea why changing the power steering sensor would cause this. I'm thinking that it has something to do with reseting the check engine light? I would be thankful for any help that is offered.
