I have a 2000 Sonoma with 210,000 miles. It will not go over 2200 rpm. No power. I have changed the fuel filter, cat converter(It had never been changed) and plugs. Fuel pressure is 60 pounds(at idle) Compression checks about 180 to 200 on each cylinder. I have heard about issues with the timing chain tension-er, but not sure what the symptoms are. Any knowledgeable advice appreciated. Thanks in Advance for looking.
