Well I bought a 99 s10 blazer 4x4 with the 5 speed. Thought it would be cool well now the 4x4 selector switch stays lit all auto4 4high 4low neutral. Wherection do I search everything I've seen is all the lights are out. Also I have a multi cylinder miss fire I've been chasing the guy I purchased it from just told me today that he changed all the plugs but 1 the difficult one on the drivers side I'll change that bit I would assume that would be the only cylinder not multiple. Also I just changed the cap rotor and wires engine coil and ignition control module. I also checked the egr valve and replaced the upper intake gasket cause the fuel pressure regulator was bad alls together and now it hesitates till you drive it for awhile then you can turn it off and it acts like it's cold for awhile then runs fine again. Help I'd like to get my 4x4 working before the iowa winters hit.
