Engine hesitates

I have a 1994 Dodge Intrepid - 154K. Between 1700-2000rpm, whether hot or cold, engine hesitates and stumbles. Full power above and below these rpm's. This occurs whether in park and reved up, in overdrive or in D3. No codes stored in computer.

Compression is ok and so is fuel pump and fuel pressure. TPS, O2 sensors test fine.

NEW: Plugs, wires, coil pack, cam and crank position sensors, IAC, ECT, EGR and EET, air cleaner - throttle body clean.

Any suggestions?

You may also want to check the voltage being regulated by the alternator.

You dont mention replacing the TPS. This could have a flat spot at that particular throttle opening?
