Cylinder 1 misfire code is almost always a bad drive belt, primary clutch, or both. Once you replace the parts you need and run it over 4000 RPM for a couple minutes, if the code doesn't clear, you might have other clutch issues. The only other check engine light issues we've seen over the years is usually electrical and it's almost always a pinched wire in one of three places. The wires are usually fuel delivery related. I wouldn't bother with trying a new injector, those hold up very well. Start with a fuel pump if you confirm it isn't pumping. If it is and you still have a problem, it will be a pinched wire. We see 2 or 3 of these every year. Once we see that issue this year, we'll do a video on it. Normally the pinched wire will be in the main harness toward the left rear of the vehicle where it rubs against the frame. The other area is under the intake box. There is a small harness that rubs under it as well. [ Ссылка ]
