Love this site and have learned tons from just bumping around here... I have a thread started on a fuel flow issue that I have not got a response to, so I figured I would post here as well... I realize that there are not supposed to be tech ?s here, but I am getting desperate. I don't want to spend $250 on an IPS and find out it is the IP. Does a new IP include the IPS on it?

I have a bitchin 1993 non turbo IDI A/T ambulance that has run great for 3 years, but is now having what I think is an electronic fuel relay problem. Almost 200k on her, runs and idles well (does take longer to start though...), but when you mash the throttle, fuel seems to be cutting out intermittently. At its worst it will throttle for 2 seconds and cut out for one and so on. I can drive it if I am light on the pedal and it does it FAR less. My tach also started going haywire about the same time... 0 at idle and will register under hard acceleration... Don't care about that so much unless they are related, though. I'm also running a bit hotter than usual, but suspect that has to do with the fuel flow. IPS? IP? I've been told there is no CPS in this engine. That is the extent of my abbreviation knowledge, so full part names would be appreciated please! HELP!
