i have a 91 gs and every day once my car is moving it makes a really really annoying noise that sounds like a woodpecker from under my hood. im pretty sure its the abs system cause it comes from that side. it cant be any of the belts because i just changed them all, but it sorta sounds like that. anyone have any idea what this may be ?
If the noise seems to be coming from under the battery, the problem is the ABS pump. Have a technician check your ABS system just in case. HTH
…or the accumulator could be the culprit. i’ve had that problem too, but don’t have the money to fix the system. i just disconnected my abs–now i have that permanent yellow “abs” light on in my dash… 
how did you disconnect your ABS? I disconnected mine on my '90 GS and I don’t have a light on my dash. I just pulled the 3 fuses in the engine fuse box that control the ABS…
Yea my car has that same annoying noise.
I just left mine doesn’t come on very much anymore.
