I want to state this first, I believe it is a fuel problem, but it is possible that it could be something else. My car died on me, so I checked and replaced the spark plugs because they were fouled out. The car runs, but has no power on take off. If you put the accelerator to the floor, it accelerates, but with little power until it gets up to about 2500 rpm. In doing this, I believed it was the fuel pressure regulator. Easy fix, replaced it; still have the same problem. Now I am going to change the fuel pump. I did check the fuel pressure, it read 26 psi and O.E. specs are for 30-40 psi. I am going to replace the pump and post whether or not it fixes it. might be a vaccum leak, not sure, but it's driving me nuts and I just want to put it in the river right now lol.
