From a dead stop to any speed, it felt like I no acceration. I would have to feather the gas pedal to get up to speed. I've replaced fuel filter, 02 sender ( front), maf sender ,fuel pressure regulator ,cleaned all grounds, had fuel pump tested , had head gasket checked ,changed spark plugs and wire's, cleaned throttle body and pressure cleaned fuel system. Every time I change a part or do any cleaning , the truck will run fine, for awhile , but the problem returns. I now have 150k on truck ,and I want to get 150 k more. I fell this is a extremely hazards situation. All I'm looking for is a answer to what's wrong!!!! Toyota is aware of what's wrong ,but the dealers only to keep replacing parts ($) . The Toyota forum s on web have 1000s of answer s, but, nothing definite. Please help!!!!.
