Check fuel pressure, bad pressure relay or pump

they sell very unexpensive code readers at autoparts not the digital but the one with a little bliking light you might be hable to pull codes with it

this is the problem with code readers they bwill tell you the code and sometimes even have a reset feature. However they do not tell you the parameters and don't have an drivability feature so you can not test the ecm and all the sensors or modules while engine is running. diagnostic scan tools are very expensive and hard to use unless you have been trained to do so and PEP BOYs is not what I call real reliable mechanics to begin with. Now I concure with toddG on his reasoning in what might be the potential fault. if your vehicle is running rich or lean your O2 sensor will pick this up on the exaust side, however it is not the sole sensor responsible for the ecm adjusting the fuel air mixture.. you stated that you have switched out several o2 sensors and the fuel pressure regulator, but there is also you mass air flow sensor, your TPS sensor, as well as your map sensor these are worth checking out and just because a faulty sensor is the problem doesn't mean you will get a code each time. the system is built with redundancy in order to keep the vehicle running. in order to get the best possible diagnois take it to a shop where they have a full diagnostic scanner this will have not only OBD1 and OBD2 but cam protocol as well. while the tech is scanning the vehicle he will be able to see how the engine is performing under realtime conditions. please rate this as well as change the rating for toddg because he did offer a valid suggestion

take the car to the trasmission guy, have them check it out.
you may have burn the troque converter.
SOURCE: 98 ford Exped. oil and engine light come on but go off on restart
did you check the transmission heat sensor or the intake air sensor these can be incorporated with temp guage on some vehicles
but theres also the problem of alternator is getting ready to give only
take an electro meter and hook up to cigarette lighter with a 2 post power maker and watch the voltage as your driving try to recreate the conditions that brought this about if the reading changes dramatically this will tell your alternator will need to be replaced at some point also dead cells in battery creates this little bump in electrical

sounds like a maf issue was it new?171/4 is usually uim vac leak
