Service Engine Soon -light

Hi forum

Got a 97 6.5TD Tahoe, and my Service Engine Soon-light has turned on. Is there at tool/software I can use for diagnostics, which is windows compatible/based? (and dosen't cost the same as my car) I had a GMC Syclone before, and I had a DOS-program for running diagnostics on that car..

So.. if any of you out there know about such a tool, please give me a hint.. Need to know whats wrong with my baby ;D

T ac S, my SES light comes on now and then, usually when I try and pull one particular long hill around here.
Each time a simple can of 'dry gas' ie. isopropyl has cured the problem.

Thanks for your answer

Took my car to the repair shop, they hooked it to a computer and the reason why my SES-light went on, was air in fuel. Not a big problem, but could indicate a near failure of the pump (Not main pump, but the "little one")

REPLACE THE GAS CAP FIRST

(yes that's in all caps for a reason)
