Clogged Cat
I recently replaced the engine in a 1998 dodge ram that had 3 dead cylinders and filled the exhaust with oil. Since the motor swap the truck seems like it has less power than it should. I have checked all the sensors with my scanner and put a vacuum gauge on and everything is working properly, the truck has been getting around 10 mpg and is throwing a left bank efficiency light on occasion. Does it sound like the cat is clogged?
