Been through the fuel system (fpr, filter 2X, injectors) and ignition (plugs, rotor, cap, wires). Even replaced tps
. Hesitation less than it was, but is still there. Also has a rough idle. Other than that it runs great. Thought it might be a fuel pressure issue. If I pull the vacuum hose off the fpr with the engine running the fuel pressure goes to 40psi, rpm goes up and runs nice and smooth.
