The loss of power feels like the engine is only using 4 cyl instead of all 6. I am not getting any trouble codes from the ecm. The jets are spraying gas fine (cone shaped) into the carb. I have the manufacturer's manuals but don't help with diagnosing problems. I dont have alot of time to try this or try that trying to solve the problem or money to buy different parts hoping to get it running right.

George, when was your last tune up? 244,000 miles may need to compression test all cylinders, remove all plugs, disable the fuel system by removing the fuel pump relay, and then compression test each cylinder.
