d16y8 having a jerking problem around 45mph+ when letting go of the gas. check engine light was on for the ICAV, it was replaced. the intake manifold gasket was leaking also replaced. car idle sits at 1100 and will not go down any more. could this be a tps problem? any info would be appreciated.

Hard to diagnose over the internet but it sounds like you might still have a slight vacuum leak. Or a bad IACV.

just changed intake manifold gasket that was leaking and switched out the icav for another but its still doing the same thing.
