HESITATION WHEN ACCELERATING OR GOI

1994 Cadillac Fleetwood

Engine Performance problem
1994 Cadillac Fleetwood V8 Two Wheel Drive Automatic 141200 miles

Fleetwood hesitates badly when given gas to accelerate or go up a modest hill. Seems to be worse when raining or damp out.

I've changed oxygen sensors and throttle position sensor with no change in performance.

MAP sensor and fuel pump have been suggested as being the problem. I have a MAP sensor connector but not a MAP sensor itself.

What do you think?

Thank you,

Hi: It seems interesting that it's wors when it's damp outside. Has the vehicle had a tune-up reciently? Also, have you had the computer scanned for trouble codes? Most nationally recognized parts stores will do it for free. I recommend having it done.

Let me know what you find.
