92 Estate Wagon no power 5.7 off idle TBI

[ulremember]

Good day. My issue is this: car idles great. As soon as i give it a bit of gas in drive, iget hiccups and no power. I have changed, injectors, map sensor, tps and the fuel pump ( about 2 years ago Autozone brand)
My timing is set @ 0 degrees. When i changed the injectors, i did not mess with the regulator.

Any suggestions as to where to look next. Car has 210,500 mile and when she was not hiccuping, RUNS GREAT and pretty good on gas.

Thank you in advance.
Blessings

Start by checking fuel pressure, 10-13 psi, change the fuel filter this is where to take the fp readings anyway. If the the tps is the adjustable type, make sure it is set right, timing was set with reference wire disconnected, correct?
