Can't rev when running

[jick.cejoco]

year 2000
last thing done, replaced distributor o-ring
no, not after refuel.
don't know if the exhaust is clogged.
not sure what is throttle body by wire.
I don't know the engine vacuum

have the ignition timing checked and maybe adjusted.



chances are the ignition timing is late and should display lower than 18 inches of mercury vacuum at the intake manifold at idle speed
