1. wires, plugs rotor, cap

3. comnpression test 149 psi all cyl.
4. fuel pump 71 psi.
5. TPS smooth resistance.
6 Replaced all vacumm hoses small ones.
7. Lifted egr by hand changed idle.
Problem is getting worse at 1500 to 1550 rpm Runs smooth at 2000 rpm and up. Shakes so bad it will rattle your coffee cup off the dash.
Seemed to not shake at 6am with engine cold at 1550 rpm. Air cleaner removed.
Has bad valve guides. smokes.
Can an injector be bad that passes all tests?
