81 rough idle problem just started
My 81 which had been running fine all summer just started acting up. It starts and runs fine, but after warming up it just Idles very rough. Running past Idle doesn't seem bad.
Code of course gave me a bad O2 sensor which I replaced since it was cheap. That wasn't the answer.
I have checked for vacuum leaks, bad gas or fuel filter and plugs were changed last year/wire checked.
Any thoughts on where to go next. Thanks in advance for any suggestions.
