Narrative:
Flight from mex to dfw. #3 throttle had to be advanced to the fire wall to achieve approximately 2.00 EPR. Normal power setting was 2.12. The captain thought the EPR was in error as N1 and other engine INS matched engines 1 and 2. We continued to dallas uneventfully and wrote up the problem. Later it was found that a bleed valve was missing from the engine. In retrospect, we should have aborted and had the problem investigated further before continuing.

Title: ACR LGT CONTINUED TKOF WITH ENGINE EPR READING LOW AT FULL FORWARD THRUST LEVER POSITION.
Narrative: FLT FROM MEX TO DFW. #3 THROTTLE HAD TO BE ADVANCED TO THE FIRE WALL TO ACHIEVE APPROX 2.00 EPR. NORMAL PWR SETTING WAS 2.12. THE CAPT THOUGHT THE EPR WAS IN ERROR AS N1 AND OTHER ENG INS MATCHED ENGS 1 AND 2. WE CONTINUED TO DALLAS UNEVENTFULLY AND WROTE UP THE PROB. LATER IT WAS FOUND THAT A BLEED VALVE WAS MISSING FROM THE ENG. IN RETROSPECT, WE SHOULD HAVE ABORTED AND HAD THE PROB INVESTIGATED FURTHER BEFORE CONTINUING.
