This is what the mechanic in Northern California reported:
77 corolla diagnostic- wont go over 35mph or up hills
suspected coils or massive exhaust leak (back pressure) or head Gasket.
Note, checked and found Catalytic converter is broken internally. I did a cylinder kill test and found no.3 cylinder is dead, performed compression test and found both cylinders 3 and 4 have almost no compression, no.4 5psi no.3 30psi no.2 135 psi and no.1 with 145psi
Thanks RollaClub!!
