hey ive already posted several times about my car giving me issues and it wouldnt start and whatnot. but anyway i switched my fuel pump out of my 98 gsr into my 94 gsr and it starts the car after a little bit of turning over, but its been sputtering and had some harsh idles etc. doesnt drive like it use to, HUGE loss of power and acceleration. but anyway, my question being is there a difference in fuel pressures between the 98 and 94? i figured the 98 would be higher if anything, but im not too sure now. HELP!

oh and one more thing, if i were to just say forget it and get a walbro 190, does it come plug and play or do i need to get that 'install kit'

thanks

The fuel pressure between the 2 is the same. I know nothing about the walbro pump, except that it's not gonna solve your current issue.

You need to actually diagnose the problem instead of throwing parts at it. Put a fuel pressure gauge on it and see if it's within specs. How's the fuel filter? How are all the components of the ignition system?
