The ABS light comes on intermittently on my 95 Monte Z-34. I have checked all fuses, replaced the ABS relay, checked fluid level, sprayed brake cleaner on the front wheel sensors, and checked all connections. Any ideas on what else to check before I spend a ton on having the OBD-II diagnostic?

It should be scanned for abs codes to stop guess work.

mine did the same thing, it was a wheel speed sensor. check that out, might be bad.

also like max said, check for abs codes, not just general codes if you can.
