Ok, ive been working on this problem on and off for about 2 weeks. I get in, starts right up, free revs , but when I put in gear it will not go any thing past idle power until it starts rolling, then it will begin to take power.many, many people, articles tend to make you think the converters are plugged. Wrong! not clogged converters. as big a job to remove the exhaust on this engine, I did it. Now, that is acomplished, we know it is not converters. I get no trouble codes at all. Fuel trim seems fine, fuel pressure is 40 lbs running, tested the fuel pressure regulator, its ok. changed the tps . all vaccuum lines are clear, new fuel filter, spark plugs. I am looking for some advice to test other components. It starts up quickly, never overheats, just wont pull itself away from the curb even under full throttle ! it just revs a little bit . It idles so smooth. I am looking at fuel injectors possibly clogged. Help please!
