The engine idles fine but as soon as i get to over 1,500 RPM the engine acts like its starved for fuel or air??? so i changed the plugs, wires, cap, button, tps sensor, fuel filter and the fuel pump, sock and harness, still having the same problems checked the air filter its clean,under acceleration basically no power and it begins to bog down i also did a fuel pressure test and the pressure was within the manufacturers spec's before I changed the fuel pump. I am really tired of taking it to shops and having things fixed for the problem not to be resolved. Any help would be very appreciated this is my daily driver and i am having a lot of trouble getting to and from not to mention the constant horns behind me beeping because i am only able to get to 35mph and thats a struggle you guys on here seem to be very knowledgeable on this issue and your help would be a life saver. Thanks, Engelwood. 1992 S-10 blazer 4 door 4x4 Automatic 4.3 with CPI engine code "W"

Was this problem there before you changed all the parts or after?
Have you checked the cat to see if it is clogged?
Have you looked inside the plenum to see if you have a leak?
Do you have any codes?

how many miles on it? what has been replaced recently other than what is listed? did it have any work done on it just before the issues started?
