'LURCHES' AT 2000 RPM

1995 Nissan Maxima • 6 cylinder • 150,000 miles

My max starts and idles well, accelerates well until ~2000 rpm and it begins 'lurching'. I back off on the accelerator until it shifts and I am able to accelerate further(in higher gear) until I get to ~2000 rpm, again the lurching. I back off once again and to get through it and once I'm around 40 mph (and less than 2000 rpm)I can maintain and accelerate. It always seems to happen at 2000. I am also pretty certain that I have a water leak into the inlet. Could it be and air flow sensor issue?

Do you have a check engine light and when was last tune-up?

Could be the MAF and TPS sensor-to include the VSS sensor-check the fuel pressure if its within specs with and without the pressure regulator-
