i just bought a 1998 c5 corvette and the oil pressure gauge has a constant reading of 130 psi which i read is a common problem as the sensor goes haywire however i am having the fuel economy jump (the gauge for it) around cruise control wont engage and the range never changes if u leave it on distance to empty on the screen..... do these all sound like individual problems or does it sound like it needs a new ecm?

I am not familiar with vettes, you could try posting in the pcm/tuning section. One of them will probably be able to help you out with figuring out the problem.
