I own a 2000 tacoma 4x4 2.7 5 speed at 25oo rpm in 3rd gear it bucks untill 3200 on 2000 Toyota Tacoma

it will buck in 4th and 5th untill the same rpm. I have changed the 02 sensor it was flat lined, fuel filter,air fuel meter,and swapped out a known good maf.the plugs are new and there are no miss fire codes the only code that did come up once was a egr insufficient flow I have looked at my coolant sensor cold and it is reading corect.It will not buck for about 2 min cold untill temp starts to come up it runs excellent with the exception of the bucking it takes no oil or antifreeze
