surge at idle

Let me throw this out for you all to ponder. Changed plugs ,cap, rotor, and wires running good. Next changed o2 sensor and replaced tpi switch set to .59volts .fuel mileage is 25+on the highway with my foot in it pulls great. Still feel surge when hot and at idle.Also notice tach and volt meter jump with surge, not sure if it is cause or result of surge,also it seems more pronouced at nite with lites on. Only code was 22 low tpi since reset.anybody have the same trouble? thinking alt or poor ground in charge system.

I think you are right here. I have the same issue and it seemed to have started when I replaced the battery. The ground cable to battery connector was corroded. Replaced it but I have not had a chance to check the other end yet. I bet it is the same.
