I traced back to the firewall and there is only 4 volts there too. My gauge reads low and I suspect the low voltage is effecting things, idle and performance. The computer thinks the engine is not up to temp. Any ideason how to fix it and what it could be effecting. There is the proper voltage at the other sensors I have checked.

Crap, the guru strikes again, without doing it himself. Haynes manual says approximately 5 volts!!!!!!! I'll go with the guru number.

Thanks, guess I can't put the blame for poor idle there.:banghead Still Tweecing to get it to run perfecto!
