Have you checked the catalytic converter? what was the fuel pressure at? should be 58psi. fuel volume looks good. no codes I assume? camshaft position sensor good? If no codes I assume so... back to the converter... do you have a scanner to look at fuel trims and upstream/downstream o2's?
I HAVE CHECKED ALL SENSOR ALSO LOAD TESTED SENSOR CIRCUITS CAM AND CRANK IS IN ZINC READING 4 DEG AND HAVE EVEN REMOVED THE CAT CONV FUEL PRESSURE IS READING 60 PSI AND DOSENT FALL ON A HARD EXCEL INJECTOR SPRAY PATTERN IS VERY EVEN AS WELL
Ok, have you done a compression test? How many miles on the engine. Describe the circumstances under which this problem started. (ie - what happened right before this problem started.)
