check your fuel pressure...."with the key 'on' listen for the pump running" check the vacuum connection to your fuel pressure regulator....replace butyl rubber hoses with silicone ones~

your TPS could be all worn out...you might test and/or replace it...it is a high wear item where man meets machine there will always be trouble~
