Note I have a friend, his 95 had original wires and at idle we kept hearing knocking noise from the firewall bank. As it revved up the missing was more noticeable. Found the wire spark plug end/boot was arcing inside tube. As a temporary fix/test spread silicon rubber on the sides of the boot and let cure for about 20 minutes. (Do let any of the fumes from silicon rubber get suck into the intake!) Not good for O2's That was two years ago and he's driving that way.
IRMC it should be in the achieves, but I found my circuit board (connector pins where cracked). resoldered and haven't had it act up once. Note I never had codes even when it did fail to open. Also don't forget to lube. I finally placed a teaspoon size of yellow wheeling bearing grease on the gears. I put nylon 3/8" spacers between the IMRC and was able to reuse the original bolts. Beauty cover on, still working flawless. Did this last spring so knocking on wood it stays flawless. 54k miles probably need to be thinking about pulling the UIM inspecting how the normal build is progressing.
