There are three engine options for that car which model or engine do you have? I would start by rechecking my timing marks on the timing belt. If you had to drastically move the distributor after replacing the timing belt to set the ignition timing your camshaft timing may be off. Check engine manifold vacuum it should be 21inchs at idle if it low your cam timing is probably off. Check the basics, any vacuum hoses off or mis-routed. How does the car idle and start from cold?
