Engine Performance problem
1992 Chevy S-10 6 cyl Four Wheel Drive Automatic 200, 00 miles
My s10 blazer has a V6with CPI, recently the engine started acting up almost like it wasn't getting enough fuel. So I started with the fuel filter, it still ran the same next came the new fuel pump, same results. My attention shifted to spark, I replaced the coil, plugs, plug wires cap & rotor and had the ignition module tested. After all this it ran exactly the same, so I switched gears again and replaced the TPS and the oil pressure sensor.I am running out of things to replace and money to replace them, after listening to the engine more closely it almost sounds like its getting too much fuel because if you are driving it you can get it to clear out and run properly until you let off on the gas. My next move was to replace the fuel pressure regulator but I'm going to wait for some more advice. Replaced fuel pressure regulator this afternoon and the problem is still there and maybe has gotten a little worse. Engine will idle fine and problem begins when you step on the gas, but can relieve itself if you gently let off the gas.I don't have a clue!Any help would be greatly appreciated.
