idles smooth but sputters and stalls on acceleration then smooth.

I think u r right. another mechanic said the same thing. Thanks.

scan shows no faults but 93's dont show fuel pressure. Thanks for response

I know that! However a 'proper scanner' with live data can privide useful info as to what your problem is! Low fuel pressure should result in a lean condition. If it is that at all. TPS readings? Fuel trim & 02 readings?? Fuel tank clean inside with no water or new tank?

Fuel tank used but very clean inside. using a pressure/flow gauge on tuesday. That should verify the pump, TPS might do similar but condition is worse at an up hill stop and go.
