Hi friends. I have a Puzzler-worthy issue going on with my 2002 Jeep Liberty (LTD, 4WD, V6). A few weeks ago (Christmas Eve!) it started to stutter when slowing down to a stop, and then – after a few times of doing that – began the bigger problem of completely stalling out/shutting off once at a stop (in traffic, at a light/stop sign). It starts up fine and idles fine from a stopped position; it’s only when I drive and slow down and come to a complete stop that it has the issue. The shop I go to is a great Jeep-based shop, and they’ve:
- serviced the (quality, few-year-old Interstate brand) battery. Initially, it was a bit drained, but they charged it up and made sure nothing else was draining it. I went to drive it home but it had the issue, so brought it back.
- cleaned the idle control sensor. They found it was a bit gummed up, affecting airflow under 10MPH. Said that did the trick for them with multiple test drives but then I went to drive it home last night and it did some stuttering on the way home when I started coming to a stop. I tried not to get frustrated; “Maybe it’s going to stutter a wee bit now and then,” I thought. “No complete stall-outs = good.” But this morning driving to work it stalled out nearly every time I came to a stop. I took it back in and they’re going to keep investigating.
The issue is a bit frustrating since we had just gotten a major engine repair around $3500 due to coolant leaking into the engine (the heat wasn’t working and that was apparently why). We figured $3500 was still worth at least 5 more years of driving (the car has ~120K miles) rather than start looking for a new or new-used car for 3 or 4X that price. But now this.
Any ideas welcome; I trust Golden Gate Jeep but figured I’d put it out there for any ideas or just plain Puzzler enthusiasts
