Re: Is there a difference between a Fuel Pressure Sensor and a MAP sensor? (Oceans60R)
Not even close Oceans. I know it can't be the plugs at this point, and the FPS should be throwing a code, according to other threads I've read (signal too high or low or pressure too high or low). The stuttering is intermittent. It will pull fine until, lets say 2500rpm, then stutter until 3k then pull fine again until 4500, then stutter again until 5k (these are not actual RPM, this is an example).

It sounds like my recent experience - small stuttering that grew into full blown stalling and sitting by the side of the road. On a trip back from the east coast - I drove 1,500 kms with a very sensitive fuel pressure sensor that would cause the car to cough and sputter and eventually die whenever it decided to act up.
Was diagnosed easily at the dealer in Maine and replaced upon return home. Seemed to work fine up to about 2,500 rpm if treated gently and correct itself (for a while) after sitting.
