irregular idle
 

My idle just stared to be surging last nite for the first time. The only thing that has changed was I installed a battery cut off switch. Which of course meant, the negative cable was off for a few minutes.

Run the throttle Body Adaptation proceedure...
If that doesnt do it, clean your throttle Body and also get a can of Mass Airflow sensor cleaner and clean it good... then give it a shake and let it dry. It's alcohol based so it dries quick!

That should do the trick unless you have a vac leak or defective MAF sensor.

irregular idle
 

wow after two car cruise ins (wed n sat) idle became regular again. And one little street race shifting at 6500 through 3 gears

Is this where you put the key in, turn it to the right for a minute and then take it out, and then put it back in?
