Hello, I'm new to the group and I have a problem with my truck, I hope you can help me. I was driving my truck two days ago, it's a 2001 Ford Ranger 2.5, I stopped at a stop and everything was fine, and after driving for a minute it suddenly lost power and when I accelerated it didn't make any power and the engine sounded different, I stopped at a gas station and turned it off and on and it did the same thing, but now it's shaking like it wants to turn off or as if it had a plug in the exhaust, we towed it home and now it shakes when I turn it on and it sounds like the catalytic converter is clogged and I get codes for cylinders 2 & 3, I already changed the spark plugs, and I changed the timing belt and it still does the same thing, can someone help me?
