Disconnected battery like you said, but code was still there. Took carb apart again to check tps and it was broke. Go figure. Must have broke it while reassembling. Anyhow, bought a new one from Autozone, put it in, and carefully put the carb together again, started it up and everything was good. No more trouble codes. Now I just have to remember how to set the clock on the radio. Thanx guys.
