Hello, im not quite following your no compression in high gear, do you mean it has a lack of power at highway speeds? It has a surging idle and wants to stall at stop? How many miles are on the engine? Is the check engine light on and have you had it checked for codes with a scan tool? No vacuum leaks??

as soon as u go into high gear the power drops off. and the check engine light is on. can't find any vacuum leaks,it has 115000 miles on it.

Ok with the check engine light coming on in unison with the issue, we need to know what code(s) is being stored. Most auto parts stores will pull codes for free. Could be a fuel pump issue, vacuum leak, or something else. WOnt be sure until you run a diagnostic on the car first
