Engine Performance problem
2000 GMC Safari 6 cyl Two Wheel Drive Automatic 153000 miles
At wide open throttle engine boggs down badly. It starts right up and pures it even runs good most of the way through the throttle range if I apply the throttle slowly but if I mash the throttle to the floor it instantly starts bogging out. Scanned for codes and their are none. All sensors seem to look good. Checked fuel pressure and is o.K. Checked vaccume and it is also good. I disconnected cat and checked but engine still runs the same. At this point I switched out injector assembly and still have same issue. I am A.S.E. Certified and completely stumpped. Unfortunetly this is for a family member and I am making nothing off of it. Please help. If needed I can be reached at (260) 471-2277 monday morning at which time I will gladly give you a credit card # for your time. Thank you in advance for your help.
sincerely Alan S.
