2002 Sahara manual, ~142000 miles, no codes reported
Last week when I pulled into a parking spot the issue started - my idle would drop to the point of almost stalling. The issues persisted and I diagnosed as best I could finding that the low idle only occurred at a complete stop but if I tried to gas the engine slightly (at idle) it would stall. Cruising at idle presents no drop in RPMs to match what is happening at a dead stop. I believe the IAC needs some cleaning and I plan on doing that ASAP.
However, this morning I had to move the Jeep from my driveway to the garage and it stalled hard. I was able to restart the engine but only by applying gas while cranking the engine. After some fancy stick/gas/ebrake work I was able to get into the garage stalling about 3 more times. This is where it gets weird - once in the garage it did not stall (I expected to have to coast in) and idle seemed normal. I did not have time to play around as I did not have time.
I do have a bluetooth OBD dongle that I will hookup to see if anything weird is reported, but 2002 doesn't seem to be new enough to give super awesome data.
Besides cleaning the IAC is there anything I should be looking for/at? Thanks!
