Running rich

Hi group

My frequency valve is not buzzing, i have tested the pin 3 on the diagnostic plug and direct to the frequency valve using a frequency meter and a scope and there is no nice 'square' wave in fact there is very little. There is +12v though.
I was told solonoids are very reliable, but its possible in extreme hot and cold that it could cause them to stop working which could effect the ECU too. My car was left outside in NJ for around 8 years.

Also my cat was glowing red, could the frequency valve not working cause this?

Any ideas?

Thanks
