Car Pulses during accel and cruising?

Did you properly adjust the TPS..you know jumping the initial set coupler and blah blah blah. Are you 100% sure you have no vacuum leaks? They can seal and open in relation to engine temperature. I would check between the extension manifold and the LIM...its common that people remove the upper intake assembly from there and its possible that constant improper removal process has warped the manifold or made the gasket fail.
