98 S10 truck, intermittent guage problem
My father in law's 1998 Chevy S-10 truck will intermittently lose all guage indicationswhen driving. (speed, RPM, lights, oil, heat, etc.). The truck runs fine, and will not disengage the cruise control when this happens.
Any suggestions? I assume the ground wires need to be checked?

RE: 98 S10 truck, intermittent guage problem
Check the EGR Valve, my 97 Blazer had similar problem and what happens is carbon build up in the intake flakes off . It then will cause the EGR valve to stick open intermittently, which causes the engine to lose intake manifold pressure, (in other words shuts the engine off, until the carbon clears the valve). This is a common problem on vortec engine that have an EGR Valve. Later models do not have one, my 2002 S-10 ZR2 does not.

RE: 98 S10 truck, intermittent guage problem
I had two of the above problems on my 94
a) chasis ground bad - Although this caused not only the dash to light up and die but also the vehiclewould barely run, and even die at points, very difficult to re-start
b) EGR valve, only dash error was "check engine" truck ran poorly but still ran no other "electical" related to this issue
