I was told that my engine was bad that I need fuel injectors put in from the previous owner but when I took it by the shop, they told me that I need a new engine Due to a misfire on cylinder 1 and cylinder 2. The Intake Manifold is broken off from the coil pack in the back. The vehicle won't go past 25 MPH. When it shifts to 2nd gear i have no power output. Please help
